Device, method, and graphical user interface for selecting user interface objects

ABSTRACT

An electronic device with a display, touch-sensitive surface and one or more sensors to detect intensity of contacts with the touch-sensitive surface displays a virtual keyboard, and outputs characters corresponding to respective keys in the virtual keyboard when character-output criteria are met. While displaying an autocorrect user interface for changing a string of characters to a modified string of characters, the device detects an autocorrect input that includes an increase in intensity of a contact above a first intensity threshold while a focus selector is over a respective user interface element in the autocorrect user interface, and then either changes the string of characters to the modified string of characters, or maintains the string or characters, depending on whether the contact has an intensity that meets first predefined criteria with respect to the first intensity threshold and a second intensity threshold that is higher than the first intensity threshold.

TECHNICAL FIELD

This relates generally to electronic devices with touch-sensitive surfaces, including but not limited to electronic devices with touch-sensitive surfaces that detect inputs for manipulating user interfaces.

BACKGROUND

The use of touch-sensitive surfaces as input devices for computers and other electronic computing devices has increased significantly in recent years. Exemplary touch-sensitive surfaces include touch pads and touch screen displays. Such surfaces are widely used to manipulate user interface objects on a display.

Exemplary manipulations include adjusting the position and/or size of one or more user interface objects or activating buttons or opening files/applications represented by user interface objects, as well as associating metadata with one or more user interface objects or otherwise manipulating user interfaces. Exemplary user interface objects include digital images, video, text, icons, control elements such as buttons and other graphics. A user will, in some circumstances, need to perform such manipulations on user interface objects in a file management program (e.g., Finder from Apple Inc. of Cupertino, Calif.), an image management application (e.g., Aperture or iPhoto from Apple Inc. of Cupertino, Calif.), a digital content (e.g., videos and music) management application (e.g., iTunes from Apple Inc. of Cupertino, Calif.), a drawing application, a presentation application (e.g., Keynote from Apple Inc. of Cupertino, Calif.), a word processing application (e.g., Pages from Apple Inc. of Cupertino, Calif.), a website creation application (e.g., iWeb from Apple Inc. of Cupertino, Calif.), a disk authoring application (e.g., iDVD from Apple Inc. of Cupertino, Calif.), or a spreadsheet application (e.g., Numbers from Apple Inc. of Cupertino, Calif.).

But existing methods for performing these manipulations are cumbersome and inefficient. In addition, existing methods take longer than necessary, thereby wasting energy. This latter consideration is particularly important in battery-operated devices.

SUMMARY

Accordingly, there is a need for electronic devices with faster, more efficient methods and interfaces for manipulating user interfaces. Such methods and interfaces optionally complement or replace conventional methods for manipulating user interfaces. Such methods and interfaces reduce the cognitive burden on a user and produce a more efficient human-machine interface. For battery-operated devices, such methods and interfaces conserve power and increase the time between battery charges.

The above deficiencies and other problems associated with user interfaces for electronic devices with touch-sensitive surfaces are reduced or eliminated by the disclosed devices. In some embodiments, the device is a desktop computer. In some embodiments, the device is portable (e.g., a notebook computer, tablet computer, or handheld device). In some embodiments, the device has a touchpad. In some embodiments, the device has a touch-sensitive display (also known as a “touch screen” or “touch screen display”). In some embodiments, the device has a graphical user interface (GUI), one or more processors, memory and one or more modules, programs or sets of instructions stored in the memory for performing multiple functions. In some embodiments, the user interacts with the GUI primarily through finger contacts and gestures on the touch-sensitive surface. In some embodiments, the functions optionally include image editing, drawing, presenting, word processing, website creating, disk authoring, spreadsheet making, game playing, telephoning, video conferencing, e-mailing, instant messaging, workout support, digital photographing, digital videoing, web browsing, digital music playing, and/or digital video playing. Executable instructions for performing these functions are, optionally, included in a non-transitory computer readable storage medium or other computer program product configured for execution by one or more processors.

The method further includes, in response to detecting the first movement of the contact, moving the focus selector from a location remote from the first user interface object to the first location, and determining an intensity of the contact on the touch-sensitive surface while the focus selector is at the first location. The method also includes, after detecting the first movement of the contact, detecting second movement of the contact across the touch-sensitive surface that corresponds to movement of the focus selector away from the first location. The method further includes, in response to detecting the second movement of the contact, in accordance with a determination that the contact meets selection criteria for the first user interface object, where the selection criteria for the first user interface object include that the contact meets a predefined intensity threshold while the focus selector is at the first location, moving the focus selector and the first user interface object away from the first location in accordance with the second movement of the contact; and in accordance with a determination that the contact does not meet the selection criteria for the first user interface object, moving the focus selector in accordance with the second movement of the contact without moving the first user interface object.

In response to detecting the first movement of the contact, the processing unit is configured to: move the focus selector from a location remote from the first user interface object to the first location, and determine an intensity of the contact on the touch-sensitive surface unit while the focus selector is at the first location. The processing unit is further configured to, after detecting the first movement of the contact, detect second movement of the contact across the touch-sensitive surface unit that corresponds to movement of the focus selector away from the first location. The processing unit is also configured to, in response to detecting the second movement of the contact, in accordance with a determination that the contact meets selection criteria for the first user interface object, where the selection criteria for the first user interface object include that the contact meets a predefined intensity threshold while the focus selector is at the first location, move the focus selector and the first user interface object away from the first location in accordance with the second movement of the contact; and, in accordance with a determination that the contact does not meet the selection criteria for the first user interface object, move the focus selector in accordance with the second movement of the contact without moving the first user interface object.

DESCRIPTION OF EMBODIMENTS

The methods, devices and GUIs described herein provide visual and/or haptic feedback that makes manipulation of user interface objects more efficient and intuitive for a user. For example, in a system where the clicking action of a trackpad is decoupled from the contact intensity (e.g., contact force, contact pressure, or a substitute therefore) that is needed to reach an activation threshold, the device can generate different tactile outputs (e.g., “different clicks”) for different activation events (e.g., so that clicks that accomplish a particular result are differentiated from clicks that do not produce any result or that accomplish a different result from the particular result). Additionally, tactile outputs can be generated in response to other events that are not related to increasing intensity of a contact, such as generating a tactile output (e.g., a “detent”) when a user interface object is moved to a particular position, boundary or orientation, or when an event occurs at the device.

Additionally, in a system where a trackpad or touch-screen display is sensitive to a range of contact intensity that includes more than one or two specific intensity values (e.g., more than a simple on/off, binary intensity determination), the user interface can provide responses (e.g., visual or tactile cues) that are indicative of the intensity of the contact within the range. In some implementations, a pre-activation-threshold response and/or a post-activation-threshold response to an input are displayed as continuous animations. As one example of such a response, a preview of an operation is displayed in response to detecting an increase in contact intensity that is still below an activation threshold for performing the operation. As another example of such a response, an animation associated with an operation continues even after the activation threshold for the operation has been reached. Both of these examples provide a user with a continuous response to the force or pressure of a user's contact, which provides a user with visual and/or haptic feedback that is richer and more intuitive. More specifically, such continuous force responses give the user the experience of being able to press lightly to preview an operation and/or press deeply to push “past” or “through” a predefined user interface state corresponding to the operation.

Additionally, for a device with a touch-sensitive surface that is sensitive to a range of contact intensity, multiple contact intensity thresholds can be monitored by the device and different functions can be mapped to different contact intensity thresholds. This serves to increase the available “gesture space” providing easy access to advanced features for users who know that increasing the intensity of a contact at or beyond a second “deep press” intensity threshold will cause the device to perform a different operation from an operation that would be performed if the intensity of the contact is between a first “activation” intensity threshold and the second “deep press” intensity threshold. An advantage of assigning additional functionality to a second “deep press” intensity threshold while maintaining familiar functionality at a first “activation” intensity threshold is that inexperienced users who are, in some circumstances, confused by the additional functionality can use the familiar functionality by just applying an intensity up to the first “activation” intensity threshold, whereas more experienced users can take advantage of the additional functionality by applying an intensity at the second “deep press” intensity threshold.

Additionally, for a device with a touch-sensitive surface that is sensitive to a range of contact intensity, the device can provide additional functionality by allowing users to perform complex operations with a single continuous contact. For example, when selecting a group of objects, a user can move a continuous contact around the touch-sensitive surface and can press while dragging (e.g., applying an intensity greater than a “deep press” intensity threshold) to add additional elements to a selection. In this way, a user can intuitively interact with a user interface where pressing harder with a contact causes objects in the user interface to be “stickier.”

A number of different approaches to providing an intuitive user interface on a device where a clicking action is decoupled from the force that is needed to reach an activation threshold and/or the device is sensitive to a wide range of contact intensities are described below. Using one or more of these approaches (optionally in conjunction with each other) helps to provide a user interface that intuitively provides users with additional information and functionality, thereby reducing the user's cognitive burden and improving the human-machine interface. Such improvements in the human-machine interface enable users to use the device faster and more efficiently. For battery-operated devices, these improvements conserve power and increase the time between battery charges. For ease of explanation, systems, methods and user interfaces for including illustrative examples of some of these approaches are described below, as follows:

-   -   Many electronic devices have graphical user interfaces that         display user interface objects such as thumbnails, icons,         folders, and thumb/handles in scrubbers and slider bar. Often, a         user of an electronic device will want to select and move user         interface objects on a display. However, selecting user         interface objects sometimes includes multiple steps performed by         a user that can be confusing and time consuming for a user. The         embodiments described below provide an effective, efficient         method of determining whether or not to select a user interface         object, based on an intensity of a contact with a         touch-sensitive surface. FIGS. 5A-5AA illustrate exemplary user         interfaces for determining whether to select a user interface         object or forgo selecting a user interface object in accordance         with some embodiments. The user interfaces in FIGS. 5A-5AA are         used to illustrate the processes in FIGS. 6A-6E.     -   Many electronic devices have graphical user interfaces that         display user interface objects such as thumbnails, icons,         folders, and thumb/handles in scrubbers and slider bar on a         display. Often, a user of an electronic device will want to         select and move user interface objects on the display. However,         selecting user interface objects sometimes includes multiple         steps performed by a user that can be confusing and time         consuming for a user. The embodiments described below provide an         efficient, intuitive method, implemented on an electronic device         with a touch-sensitive surface, for determining whether to         select a user interface object, or forgo selecting a user         interface object, based on an intensity of a contact with the         touch-sensitive surface. Below, FIGS. 8A-8DD illustrate         exemplary user interfaces for selecting user interface objects.         FIGS. 9A-9E are flow diagrams illustrating a method of selecting         user interface objects. The user interfaces in FIGS. 8A-8DD are         used to illustrate the processes in FIGS. 9A-9E.     -   Many electronic devices with touch-sensitive surfaces, such as         portable multifunction devices with touch screen displays, have         graphical user interfaces with displayed virtual keyboards for         typing characters for output in, for example, e-mail messages,         notepad applications, search fields. Some methods for entering a         character or a sequence of characters (e.g., entering an input         into the device that corresponds to a request to output a         character or multiple characters) require separate contacts on a         touch-sensitive surface for each character entered. However,         entering characters with a separate contact for each character         entered can be inefficient and time consuming for a user. In the         embodiments described below, a faster and more efficient method         for accurately typing characters on a virtual keyboard is         provided where a sequence of characters can be selected with a         continuous contact in response to detecting an increase in         intensity of the contact while the contact is over keys         corresponding to the characters. In particular, FIGS. 11A-11T         illustrate exemplary user interfaces for typing characters on a         virtual keyboard. FIGS. 12A-12D are flow diagrams illustrating a         method of typing characters on a virtual keyboard. The user         interfaces in FIGS. 11A-11T are used to illustrate the processes         in FIGS. 12A-12D.

As used herein, the term “if” is, optionally, construed to mean “when” or “upon” or “in response to determining” or “in response to detecting,” depending on the context. Similarly, the phrase “if it is determined” or “if [a stated condition or event] is detected” is, optionally, construed to mean “upon determining” or “in response to determining” or “upon detecting [the stated condition or event]” or “in response to detecting [the stated condition or event],” depending on the context.

Embodiments of electronic devices, user interfaces for such devices, and associated processes for using such devices are described. In some embodiments, the device is a portable communications device, such as a mobile telephone, that also contains other functions, such as PDA and/or music player functions. Exemplary embodiments of portable multifunction devices include, without limitation, the iPhone®, iPod Touch®, and iPad® devices from Apple Inc. of Cupertino, Calif. Other portable electronic devices, such as laptops or tablet computers with touch-sensitive surfaces (e.g., touch screen displays and/or touch pads), are, optionally, used. It should also be understood that, in some embodiments, the device is not a portable communications device, but is a desktop computer with a touch-sensitive surface (e.g., a touch screen display and/or a touch pad).

In the discussion that follows, an electronic device that includes a display and a touch-sensitive surface is described. It should be understood, however, that the electronic device optionally includes one or more other physical user-interface devices, such as a physical keyboard, a mouse and/or a joystick.

The device typically supports a variety of applications, such as one or more of the following: a drawing application, a presentation application, a word processing application, a website creation application, a disk authoring application, a spreadsheet application, a gaming application, a telephone application, a video conferencing application, an e-mail application, an instant messaging application, a workout support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and/or a digital video player application.

The various applications that are executed on the device optionally use at least one common physical user-interface device, such as the touch-sensitive surface. One or more functions of the touch-sensitive surface as well as corresponding information displayed on the device are, optionally, adjusted and/or varied from one application to the next and/or within a respective application. In this way, a common physical architecture (such as the touch-sensitive surface) of the device optionally supports the variety of applications with user interfaces that are intuitive and transparent to the user.

Attention is now directed toward embodiments of portable devices with touch-sensitive displays. FIG. 1A is a block diagram illustrating portable multifunction device 100 with touch-sensitive displays 112 in accordance with some embodiments. Touch-sensitive display 112 is sometimes called a “touch screen” for convenience, and is sometimes known as or called a touch-sensitive display system. Device 100 includes memory 102 (which optionally includes one or more computer readable storage mediums), memory controller 122, one or more processing units (CPU's) 120, peripherals interface 118, RF circuitry 108, audio circuitry 110, speaker 111, microphone 113, input/output (I/O) subsystem 106, other input or control devices 116, and external port 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more intensity sensors 165 for detecting intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile outputs on device 100 (e.g., generating tactile outputs on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate over one or more communication buses or signal lines 103.

As used in the specification and claims, the term “intensity” of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch sensitive surface, or to a substitute (proxy) for the force or pressure of a contact on the touch sensitive surface. The intensity of a contact has a range of values that includes at least four distinct values and more typically includes hundreds of distinct values (e.g., at least 256). Intensity of a contact is, optionally, determined (or measured) using various approaches and various sensors or combinations of sensors. For example, one or more force sensors underneath or adjacent to the touch-sensitive surface are, optionally, used to measure force at various points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., a weighted average) to determine an estimated force of a contact. Similarly, a pressure-sensitive tip of a stylus is, optionally, used to determine a pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and/or changes thereto, the capacitance of the touch-sensitive surface proximate to the contact and/or changes thereto, and/or the resistance of the touch-sensitive surface proximate to the contact and/or changes thereto are, optionally, used as a substitute for the force or pressure of the contact on the touch-sensitive surface. In some implementations, the substitute measurements for contact force or pressure are used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the substitute measurements). In some implementations, the substitute measurements for contact force or pressure are converted to an estimated force or pressure and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure).

As used in the specification and claims, the term “tactile output” refers to physical displacement of a device relative to a previous position of the device, physical displacement of a component (e.g., a touch-sensitive surface) of a device relative to another component (e.g., housing) of the device, or displacement of the component relative to a center of mass of the device that will be detected by a user with the user's sense of touch. For example, in situations where the device or the component of the device is in contact with a surface of a user that is sensitive to touch (e.g., a finger, palm, or other part of a user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation corresponding to a perceived change in physical characteristics of the device or the component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is, optionally, interpreted by the user as a “down click” or “up click” of a physical actuator button. In some cases, a user will feel a tactile sensation such as an “down click” or “up click” even when there is no movement of a physical actuator button associated with the touch-sensitive surface that is physically pressed (e.g., displaced) by the user's movements. As another example, movement of the touch-sensitive surface is, optionally, interpreted or sensed by the user as “roughness” of the touch-sensitive surface, even when there is no change in smoothness of the touch-sensitive surface. While such interpretations of touch by a user will be subject to the individualized sensory perceptions of the user, there are many sensory perceptions of touch that are common to a large majority of users. Thus, when a tactile output is described as corresponding to a particular sensory perception of a user (e.g., an “up click,” a “down click,” “roughness”), unless otherwise stated, the generated tactile output corresponds to physical displacement of the device or a component thereof that will generate the described sensory perception for a typical (or average) user.

It should be appreciated that device 100 is only one example of a portable multifunction device, and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. The various components shown in FIG. 1A are implemented in hardware, software, or a combination of both hardware and software, including one or more signal processing and/or application specific integrated circuits.

Memory 102 optionally includes high-speed random access memory and optionally also includes non-volatile memory, such as one or more magnetic disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Access to memory 102 by other components of device 100, such as CPU 120 and the peripherals interface 118, is, optionally, controlled by memory controller 122.

Peripherals interface 118 can be used to couple input and output peripherals of the device to CPU 120 and memory 102. The one or more processors 120 run or execute various software programs and/or sets of instructions stored in memory 102 to perform various functions for device 100 and to process data.

In some embodiments, peripherals interface 118, CPU 120, and memory controller 122 are, optionally, implemented on a single chip, such as chip 104. In some other embodiments, they are, optionally, implemented on separate chips.

Audio circuitry 110, speaker 111, and microphone 113 provide an audio interface between a user and device 100. Audio circuitry 110 receives audio data from peripherals interface 118, converts the audio data to an electrical signal, and transmits the electrical signal to speaker 111. Speaker 111 converts the electrical signal to human-audible sound waves. Audio circuitry 110 also receives electrical signals converted by microphone 113 from sound waves. Audio circuitry 110 converts the electrical signal to audio data and transmits the audio data to peripherals interface 118 for processing. Audio data is, optionally, retrieved from and/or transmitted to memory 102 and/or RF circuitry 108 by peripherals interface 118. In some embodiments, audio circuitry 110 also includes a headset jack (e.g., 212, FIG. 2). The headset jack provides an interface between audio circuitry 110 and removable audio input/output peripherals, such as output-only headphones or a headset with both output (e.g., a headphone for one or both ears) and input (e.g., a microphone).

I/O subsystem 106 couples input/output peripherals on device 100, such as touch screen 112 and other input control devices 116, to peripherals interface 118. I/O subsystem 106 optionally includes display controller 156, optical sensor controller 158, intensity sensor controller 159, haptic feedback controller 161 and one or more input controllers 160 for other input or control devices. The one or more input controllers 160 receive/send electrical signals from/to other input or control devices 116. The other input control devices 116 optionally include physical buttons (e.g., push buttons, rocker buttons, etc.), dials, slider switches, joysticks, click wheels, and so forth. In some alternate embodiments, input controller(s) 160 are, optionally, coupled to any (or none) of the following: a keyboard, infrared port, USB port, and a pointer device such as a mouse. The one or more buttons (e.g., 208, FIG. 2) optionally include an up/down button for volume control of speaker 111 and/or microphone 113. The one or more buttons optionally include a push button (e.g., 206, FIG. 2).

Touch-sensitive display 112 provides an input interface and an output interface between the device and a user. Display controller 156 receives and/or sends electrical signals from/to touch screen 112. Touch screen 112 displays visual output to the user. The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output corresponds to user-interface objects.

Touch screen 112 has a touch-sensitive surface, sensor or set of sensors that accepts input from the user based on haptic and/or tactile contact. Touch screen 112 and display controller 156 (along with any associated modules and/or sets of instructions in memory 102) detect contact (and any movement or breaking of the contact) on touch screen 112 and converts the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen 112. In an exemplary embodiment, a point of contact between touch screen 112 and the user corresponds to a finger of the user.

Touch screen 112 optionally uses LCD (liquid crystal display) technology, LPD (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies are used in other embodiments. Touch screen 112 and display controller 156 optionally detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with touch screen 112. In an exemplary embodiment, projected mutual capacitance sensing technology is used, such as that found in the iPhone®, iPod Touch®, and iPad® from Apple Inc. of Cupertino, Calif.

Touch screen 112 optionally has a video resolution in excess of 100 dpi. In some embodiments, the touch screen has a video resolution of approximately 160 dpi. The user optionally makes contact with touch screen 112 using any suitable object or appendage, such as a stylus, a finger, and so forth. In some embodiments, the user interface is designed to work primarily with finger-based contacts and gestures, which can be less precise than stylus-based input due to the larger area of contact of a finger on the touch screen. In some embodiments, the device translates the rough finger-based input into a precise pointer/cursor position or command for performing the actions desired by the user.

In some embodiments, in addition to the touch screen, device 100 optionally includes a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad is, optionally, a touch-sensitive surface that is separate from touch screen 112 or an extension of the touch-sensitive surface formed by the touch screen.

Device 100 also includes power system 162 for powering the various components. Power system 162 optionally includes a power management system, one or more power sources (e.g., battery, alternating current (AC)), a recharging system, a power failure detection circuit, a power converter or inverter, a power status indicator (e.g., a light-emitting diode (LED)) and any other components associated with the generation, management and distribution of power in portable devices.

Device 100 optionally also includes one or more optical sensors 164. FIG. 1A shows an optical sensor coupled to optical sensor controller 158 in I/O subsystem 106. Optical sensor 164 optionally includes charge-coupled device (CCD) or complementary metal-oxide semiconductor (CMOS) phototransistors. Optical sensor 164 receives light from the environment, projected through one or more lens, and converts the light to data representing an image. In conjunction with imaging module 143 (also called a camera module), optical sensor 164 optionally captures still images or video. In some embodiments, an optical sensor is located on the back of device 100, opposite touch screen display 112 on the front of the device, so that the touch screen display is enabled for use as a viewfinder for still and/or video image acquisition. In some embodiments, another optical sensor is located on the front of the device so that the user's image is, optionally, obtained for videoconferencing while the user views the other video conference participants on the touch screen display.

Device 100 optionally also includes one or more contact intensity sensors 165. FIG. 1A shows a contact intensity sensor coupled to intensity sensor controller 159 in I/O subsystem 106. Contact intensity sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electric force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other intensity sensors (e.g., sensors used to measure the force (or pressure) of a contact on a touch-sensitive surface). Contact intensity sensor 165 receives contact intensity information (e.g., pressure information or a proxy for pressure information) from the environment. In some embodiments, at least one contact intensity sensor is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact intensity sensor is located on the back of device 100, opposite touch screen display 112 which is located on the front of device 100.

Device 100 optionally also includes one or more proximity sensors 166. FIG. 1A shows proximity sensor 166 coupled to peripherals interface 118. Alternately, proximity sensor 166 is coupled to input controller 160 in I/O subsystem 106. In some embodiments, the proximity sensor turns off and disables touch screen 112 when the multifunction device is placed near the user's ear (e.g., when the user is making a phone call).

Device 100 optionally also includes one or more tactile output generators 167. FIG. 1A shows a tactile output generator coupled to haptic feedback controller 161 in I/O subsystem 106. Tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components and/or electromechanical devices that convert energy into linear motion such as a motor, solenoid, electroactive polymer, piezoelectric actuator, electrostatic actuator, or other tactile output generating component (e.g., a component that converts electrical signals into tactile outputs on the device). Contact intensity sensor 165 receives tactile feedback generation instructions from haptic feedback module 133 and generates tactile outputs on device 100 that are capable of being sensed by a user of device 100. In some embodiments, at least one tactile output generator is collocated with, or proximate to, a touch-sensitive surface (e.g., touch-sensitive display system 112) and, optionally, generates a tactile output by moving the touch-sensitive surface vertically (e.g., in/out of a surface of device 100) or laterally (e.g., back and forth in the same plane as a surface of device 100). In some embodiments, at least one tactile output generator sensor is located on the back of device 100, opposite touch screen display 112 which is located on the front of device 100.

Device 100 optionally also includes one or more accelerometers 168. FIG. 1A shows accelerometer 168 coupled to peripherals interface 118. Alternately, accelerometer 168 is, optionally, coupled to an input controller 160 in I/O subsystem 106. In some embodiments, information is displayed on the touch screen display in a portrait view or a landscape view based on an analysis of data received from the one or more accelerometers. Device 100 optionally includes, in addition to accelerometer(s) 168, a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) for obtaining information concerning the location and orientation (e.g., portrait or landscape) of device 100.

In some embodiments, the software components stored in memory 102 include operating system 126, communication module (or set of instructions) 128, contact/motion module (or set of instructions) 130, graphics module (or set of instructions) 132, text input module (or set of instructions) 134, Global Positioning System (GPS) module (or set of instructions) 135, and applications (or sets of instructions) 136. Furthermore, in some embodiments memory 102 stores device/global internal state 157, as shown in FIGS. 1A and 3. Device/global internal state 157 includes one or more of: active application state, indicating which applications, if any, are currently active; display state, indicating what applications, views or other information occupy various regions of touch screen display 112; sensor state, including information obtained from the device's various sensors and input control devices 116; and location information concerning the device's location and/or attitude.

Operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and/or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitates communication between various hardware and software components.

Communication module 128 facilitates communication with other devices over one or more external ports 124 and also includes various software components for handling data received by RF circuitry 108 and/or external port 124. External port 124 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling directly to other devices or indirectly over a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external port is a multi-pin (e.g., 30-pin) connector that is the same as, or similar to and/or compatible with the 30-pin connector used on iPod (trademark of Apple Inc.) devices.

Contact/motion module 130 optionally detects contact with touch screen 112 (in conjunction with display controller 156) and other touch sensitive devices (e.g., a touchpad or physical click wheel). Contact/motion module 130 includes various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining an intensity of the contact (e.g., the force or pressure of the contact or a substitute for the force or pressure of the contact) determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). Contact/motion module 130 receives contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, optionally includes determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations are, optionally, applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multitouch”/multiple finger contacts). In some embodiments, contact/motion module 130 and display controller 156 detect contact on a touchpad.

In some embodiments, contact/motion module 130 uses a set of one or more intensity thresholds to determine whether an operation has been performed by a user (e.g., to determine whether a user has “clicked” on an icon). In some embodiments at least a subset of the intensity thresholds are determined in accordance with software parameters (e.g., the intensity thresholds are not determined by the activation thresholds of particular physical actuators and can be adjusted without changing the physical hardware of device 100). For example, a mouse “click” threshold of a trackpad or touch screen display can be set to any of a large range of predefined thresholds values without changing the trackpad or touch screen display hardware. Additionally, in some implementations a user of the device is provided with software settings for adjusting one or more of the set of intensity thresholds (e.g., by adjusting individual intensity thresholds and/or by adjusting a plurality of intensity thresholds at once with a system-level click “intensity” parameter).

Contact/motion module 130 optionally detects a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns and intensities. Thus, a gesture is, optionally, detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.

Graphics module 132 includes various known software components for rendering and displaying graphics on touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast or other visual property) of graphics that are displayed. As used herein, the term “graphics” includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects including soft keys), digital images, videos, animations and the like.

In some embodiments, graphics module 132 stores data representing graphics to be used. Each graphic is, optionally, assigned a corresponding code. Graphics module 132 receives, from applications etc., one or more codes specifying graphics to be displayed along with, if necessary, coordinate data and other graphic property data, and then generates screen image data to output to display controller 156.

Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator(s) 167 to produce tactile outputs at one or more locations on device 100 in response to user interactions with device 100.

Text input module 134, which is, optionally, a component of graphics module 132, provides soft keyboards for entering text in various applications (e.g., contacts 137, e-mail 140, IM 141, browser 147, and any other application that needs text input).

GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to telephone 138 for use in location-based dialing, to camera 143 as picture/video metadata, and to applications that provide location-based services such as weather widgets, local yellow page widgets, and map/navigation widgets).

In conjunction with touch screen 112, display system controller 156, contact module 130, graphics module 132, audio circuitry 110, speaker 111, RF circuitry 108, text input module 134, e-mail client module 140, and browser module 147, online video module 155 includes instructions that allow the user to access, browse, receive (e.g., by streaming and/or download), play back (e.g., on the touch screen or on an external, connected display via external port 124), send an e-mail with a link to a particular online video, and otherwise manage online videos in one or more file formats, such as H.264. In some embodiments, instant messaging module 141, rather than e-mail client module 140, is used to send a link to a particular online video.

Each of the above identified modules and applications correspond to a set of executable instructions for performing one or more functions described above and the methods described in this application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 102 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 102 optionally stores additional modules and data structures not described above.

In some embodiments, device 100 is a device where operation of a predefined set of functions on the device is performed exclusively through a touch screen and/or a touchpad. By using a touch screen and/or a touchpad as the primary input control device for operation of device 100, the number of physical input control devices (such as push buttons, dials, and the like) on device 100 is, optionally, reduced.

The predefined set of functions that are performed exclusively through a touch screen and/or a touchpad optionally include navigation between user interfaces. In some embodiments, the touchpad, when touched by the user, navigates device 100 to a main, home, or root menu from any user interface that is displayed on device 100. In such embodiments, a “menu button” is implemented using a touchpad. In some other embodiments, the menu button is a physical push button or other physical input control device instead of a touchpad.

FIG. 1B is a block diagram illustrating exemplary components for event handling in accordance with some embodiments. In some embodiments, memory 102 (in FIG. 1A) or 370 (FIG. 3) includes event sorter 170 (e.g., in operating system 126) and a respective application 136-1 (e.g., any of the aforementioned applications 137-151, 155, 380-390).

Event sorter 170 receives event information and determines the application 136-1 and application view 191 of application 136-1 to which to deliver the event information. Event sorter 170 includes event monitor 171 and event dispatcher module 174. In some embodiments, application 136-1 includes application internal state 192, which indicates the current application view(s) displayed on touch sensitive display 112 when the application is active or executing. In some embodiments, device/global internal state 157 is used by event sorter 170 to determine which application(s) is (are) currently active, and application internal state 192 is used by event sorter 170 to determine application views 191 to which to deliver event information.

In some embodiments, application internal state 192 includes additional information, such as one or more of: resume information to be used when application 136-1 resumes execution, user interface state information that indicates information being displayed or that is ready for display by application 136-1, a state queue for enabling the user to go back to a prior state or view of application 136-1, and a redo/undo queue of previous actions taken by the user.

Event monitor 171 receives event information from peripherals interface 118. Event information includes information about a sub-event (e.g., a user touch on touch-sensitive display 112, as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I/O subsystem 106 or a sensor, such as proximity sensor 166, accelerometer(s) 168, and/or microphone 113 (through audio circuitry 110). Information that peripherals interface 118 receives from I/O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

In some embodiments, event monitor 171 sends requests to the peripherals interface 118 at predetermined intervals. In response, peripherals interface 118 transmits event information. In other embodiments, peripheral interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and/or for more than a predetermined duration).

In some embodiments, event sorter 170 also includes a hit view determination module 172 and/or an active event recognizer determination module 173.

Hit view determination module 172 provides software procedures for determining where a sub-event has taken place within one or more views, when touch sensitive display 112 displays more than one view. Views are made up of controls and other elements that a user can see on the display.

Another aspect of the user interface associated with an application is a set of views, sometimes herein called application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of a respective application) in which a touch is detected optionally correspond to programmatic levels within a programmatic or view hierarchy of the application. For example, the lowest level view in which a touch is detected is, optionally, called the hit view, and the set of events that are recognized as proper inputs are, optionally, determined based, at least in part, on the hit view of the initial touch that begins a touch-based gesture.

Hit view determination module 172 receives information related to sub-events of a touch-based gesture. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies a hit view as the lowest view in the hierarchy which should handle the sub-event. In most circumstances, the hit view is the lowest level view in which an initiating sub-event occurs (i.e., the first sub-event in the sequence of sub-events that form an event or potential event). Once the hit view is identified by the hit view determination module, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

Active event recognizer determination module 173 determines which view or views within a view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of a sub-event are actively involved views, and therefore determines that all actively involved views should receive a particular sequence of sub-events. In other embodiments, even if touch sub-events were entirely confined to the area associated with one particular view, views higher in the hierarchy would still remain as actively involved views.

Event dispatcher module 174 dispatches the event information to an event recognizer (e.g., event recognizer 180). In embodiments including active event recognizer determination module 173, event dispatcher module 174 delivers the event information to an event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores in an event queue the event information, which is retrieved by a respective event receiver module 182.

In some embodiments, operating system 126 includes event sorter 170. Alternatively, application 136-1 includes event sorter 170. In yet other embodiments, event sorter 170 is a stand-alone module, or a part of another module stored in memory 102, such as contact/motion module 130.

In some embodiments, application 136-1 includes a plurality of event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a respective view of the application's user interface. Each application view 191 of the application 136-1 includes one or more event recognizers 180. Typically, a respective application view 191 includes a plurality of event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface kit (not shown) or a higher level object from which application 136-1 inherits methods and other properties. In some embodiments, a respective event handler 190 includes one or more of: data updater 176, object updater 177, GUI updater 178, and/or event data 179 received from event sorter 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177 or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views 191 includes one or more respective event handlers 190. Also, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in a respective application view 191.

A respective event recognizer 180 receives event information (e.g., event data 179) from event sorter 170, and identifies an event from the event information. Event recognizer 180 includes event receiver 182 and event comparator 184. In some embodiments, event recognizer 180 also includes at least a subset of: metadata 183, and event delivery instructions 188 (which optionally include sub-event delivery instructions).

Event receiver 182 receives event information from event sorter 170. The event information includes information about a sub-event, for example, a touch or a touch movement. Depending on the sub-event, the event information also includes additional information, such as location of the sub-event. When the sub-event concerns motion of a touch, the event information optionally also includes speed and direction of the sub-event. In some embodiments, events include rotation of the device from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation (also called device attitude) of the device.

Event comparator 184 compares the event information to predefined event or sub-event definitions and, based on the comparison, determines an event or sub-event, or determines or updates the state of an event or sub-event. In some embodiments, event comparator 184 includes event definitions 186. Event definitions 186 contain definitions of events (e.g., predefined sequences of sub-events), for example, event 1 (187-1), event 2 (187-2), and others. In some embodiments, sub-events in an event 187 include, for example, touch begin, touch end, touch movement, touch cancellation, and multiple touching. In one example, the definition for event 1 (187-1) is a double tap on a displayed object. The double tap, for example, comprises a first touch (touch begin) on the displayed object for a predetermined phase, a first lift-off (touch end) for a predetermined phase, a second touch (touch begin) on the displayed object for a predetermined phase, and a second lift-off (touch end) for a predetermined phase. In another example, the definition for event 2 (187-2) is a dragging on a displayed object. The dragging, for example, comprises a touch (or contact) on the displayed object for a predetermined phase, a movement of the touch across touch-sensitive display 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

In some embodiments, event definition 187 includes a definition of an event for a respective user-interface object. In some embodiments, event comparator 184 performs a hit test to determine which user-interface object is associated with a sub-event. For example, in an application view in which three user-interface objects are displayed on touch-sensitive display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user-interface objects is associated with the touch (sub-event). If each displayed object is associated with a respective event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler associated with the sub-event and the object triggering the hit test.

In some embodiments, the definition for a respective event 187 also includes delayed actions that delay delivery of the event information until after it has been determined whether the sequence of sub-events does or does not correspond to the event recognizer's event type.

When a respective event recognizer 180 determines that the series of sub-events do not match any of the events in event definitions 186, the respective event recognizer 180 enters an event impossible, event failed, or event ended state, after which it disregards subsequent sub-events of the touch-based gesture. In this situation, other event recognizers, if any, that remain active for the hit view continue to track and process sub-events of an ongoing touch-based gesture.

In some embodiments, a respective event recognizer 180 includes metadata 183 with configurable properties, flags, and/or lists that indicate how the event delivery system should perform sub-event delivery to actively involved event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate how event recognizers interact, or are enabled to interact, with one another. In some embodiments, metadata 183 includes configurable properties, flags, and/or lists that indicate whether sub-events are delivered to varying levels in the view or programmatic hierarchy.

In some embodiments, a respective event recognizer 180 activates event handler 190 associated with an event when one or more particular sub-events of an event are recognized. In some embodiments, a respective event recognizer 180 delivers event information associated with the event to event handler 190. Activating an event handler 190 is distinct from sending (and deferred sending) sub-events to a respective hit view. In some embodiments, event recognizer 180 throws a flag associated with the recognized event, and event handler 190 associated with the flag catches the flag and performs a predefined process.

In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver event information to event handlers associated with the series of sub-events or to actively involved views. Event handlers associated with the series of sub-events or with actively involved views receive the event information and perform a predetermined process.

In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates the telephone number used in contacts module 137, or stores a video file used in video player module 145. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates a new user-interface object or updates the position of a user-interface object. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends it to graphics module 132 for display on a touch-sensitive display.

In some embodiments, event handler(s) 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of a respective application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

It shall be understood that the foregoing discussion regarding event handling of user touches on touch-sensitive displays also applies to other forms of user inputs to operate multifunction devices 100 with input-devices, not all of which are initiated on touch screens. For example, mouse movement and mouse button presses, optionally coordinated with single or multiple keyboard presses or holds; contact movements such as taps, drags, scrolls, etc., on touch-pads; pen stylus inputs; movement of the device; oral instructions; detected eye movements; biometric inputs; and/or any combination thereof are optionally utilized as inputs corresponding to sub-events which define an event to be recognized.

FIG. 2 illustrates a portable multifunction device 100 having a touch screen 112 in accordance with some embodiments. The touch screen optionally displays one or more graphics within user interface (UI) 200. In this embodiment, as well as others described below, a user is enabled to select one or more of the graphics by making a gesture on the graphics, for example, with one or more fingers 202 (not drawn to scale in the figure) or one or more styluses 203 (not drawn to scale in the figure). In some embodiments, selection of one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, right to left, upward and/or downward) and/or a rolling of a finger (from right to left, left to right, upward and/or downward) that has made contact with device 100. In some implementations or circumstances, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

Device 100 optionally also includes one or more physical buttons, such as “home” or menu button 204. As described previously, menu button 204 is, optionally, used to navigate to any application 136 in a set of applications that are, optionally executed on device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on touch screen 112.

In one embodiment, device 100 includes touch screen 112, menu button 204, push button 206 for powering the device on/off and locking the device, volume adjustment button(s) 208, Subscriber Identity Module (SIM) card slot 210, head set jack 212, and docking/charging external port 124. Push button 206 is, optionally, used to turn the power on/off on the device by depressing the button and holding the button in the depressed state for a predefined time interval; to lock the device by depressing the button and releasing the button before the predefined time interval has elapsed; and/or to unlock the device or initiate an unlock process. In an alternative embodiment, device 100 also accepts verbal input for activation or deactivation of some functions through microphone 113. Device 100 also, optionally, includes one or more contact intensity sensors 165 for detecting intensity of contacts on touch screen 112 and/or one or more tactile output generators 167 for generating tactile outputs for a user of device 100.

FIG. 3 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface in accordance with some embodiments. Device 300 need not be portable. In some embodiments, device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a child's learning toy), a gaming system, or a control device (e.g., a home or industrial controller). Device 300 typically includes one or more processing units (CPU's) 310, one or more network or other communications interfaces 360, memory 370, and one or more communication buses 320 for interconnecting these components. Communication buses 320 optionally include circuitry (sometimes called a chipset) that interconnects and controls communications between system components. Device 300 includes input/output (I/O) interface 330 comprising display 340, which is typically a touch screen display. I/O interface 330 also optionally includes a keyboard and/or mouse (or other pointing device) 350 and touchpad 355, tactile output generator 357 for generating tactile outputs on device 300 (e.g., similar to tactile output generator(s) 167 described above with reference to FIG. 1A), sensors 359 (e.g., optical, acceleration, proximity, touch-sensitive, and/or contact intensity sensors similar to contact intensity sensor(s) 165 described above with reference to FIG. 1A). Memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory 370 optionally includes one or more storage devices remotely located from CPU(s) 310. In some embodiments, memory 370 stores programs, modules, and data structures analogous to the programs, modules, and data structures stored in memory 102 of portable multifunction device 100 (FIG. 1A), or a subset thereof. Furthermore, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores drawing module 380, presentation module 382, word processing module 384, website creation module 386, disk authoring module 388, and/or spreadsheet module 390, while memory 102 of portable multifunction device 100 (FIG. 1A) optionally does not store these modules.

Each of the above identified elements in FIG. 3 are, optionally, stored in one or more of the previously mentioned memory devices. Each of the above identified modules corresponds to a set of instructions for performing a function described above. The above identified modules or programs (i.e., sets of instructions) need not be implemented as separate software programs, procedures or modules, and thus various subsets of these modules are, optionally, combined or otherwise re-arranged in various embodiments. In some embodiments, memory 370 optionally stores a subset of the modules and data structures identified above. Furthermore, memory 370 optionally stores additional modules and data structures not described above.

Attention is now directed towards embodiments of user interfaces (“UI”) that is, optionally, implemented on portable multifunction device 100.

FIG. 4A illustrates an exemplary user interface for a menu of applications on portable multifunction device 100 in accordance with some embodiments. Similar user interfaces are, optionally, implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

-   -   Signal strength indicator(s) 402 for wireless communication(s),         such as cellular and Wi-Fi signals;     -   Time 404;     -   Bluetooth indicator 405;     -   Battery status indicator 406;     -   Tray 408 with icons for frequently used applications, such as:         -   Icon 416 for telephone module 138, labeled “Phone,” which             optionally includes an indicator 414 of the number of missed             calls or voicemail messages;         -   Icon 418 for e-mail client module 140, labeled “Mail,” which             optionally includes an indicator 410 of the number of unread             e-mails;         -   Icon 420 for browser module 147, labeled “Browser;” and         -   Icon 422 for video and music player module 152, also             referred to as iPod (trademark of Apple Inc.) module 152,             labeled “iPod;” and     -   Icons for other applications, such as:         -   Icon 424 for IM module 141, labeled “Text;”         -   Icon 426 for calendar module 148, labeled “Calendar;”         -   Icon 428 for image management module 144, labeled “Photos;”         -   Icon 430 for camera module 143, labeled “Camera;”         -   Icon 432 for online video module 155, labeled “Online Video”         -   Icon 434 for stocks widget 149-2, labeled “Stocks;”         -   Icon 436 for map module 154, labeled “Map;”         -   Icon 438 for weather widget 149-1, labeled “Weather;”         -   Icon 440 for alarm clock widget 149-4, labeled “Clock;”         -   Icon 442 for workout support module 142, labeled “Workout             Support;”         -   Icon 444 for notes module 153, labeled “Notes;” and         -   Icon 446 for a settings application or module, which             provides access to settings for device 100 and its various             applications 136.

It should be noted that the icon labels illustrated in FIG. 4A are merely exemplary. For example, icon 422 for video and music player module 152 are labeled “Music” or “Music Player.” Other labels are, optionally, used for various application icons. In some embodiments, a label for a respective application icon includes a name of an application corresponding to the respective application icon. In some embodiments, a label for a particular application icon is distinct from a name of an application corresponding to the particular application icon.

FIG. 4B illustrates an exemplary user interface on a device (e.g., device 300, FIG. 3) with a touch-sensitive surface 451 (e.g., a tablet or touchpad 355, FIG. 3) that is separate from the display 450 (e.g., touch screen display 112). Device 300 also, optionally, includes one or more contact intensity sensors (e.g., one or more of sensors 357) for detecting intensity of contacts on touch-sensitive surface 451 and/or one or more tactile output generators 359 for generating tactile outputs for a user of device 300.

Although some of the examples which follow will be given with reference to inputs on touch screen display 112 (where the touch sensitive surface and the display are combined), in some embodiments, the device detects inputs on a touch-sensitive surface that is separate from the display, as shown in FIG. 4B. In some embodiments the touch sensitive surface (e.g., 451 in FIG. 4B) has a primary axis (e.g., 452 in FIG. 4B) that corresponds to a primary axis (e.g., 453 in FIG. 4B) on the display (e.g., 450). In accordance with these embodiments, the device detects contacts (e.g., 460 and 462 in FIG. 4B) with the touch-sensitive surface 451 at locations that correspond to respective locations on the display (e.g., in FIG. 4B, 460 corresponds to 468 and 462 corresponds to 470). In this way, user inputs (e.g., contacts 460 and 462, and movements thereof) detected by the device on the touch-sensitive surface (e.g., 451 in FIG. 4B) are used by the device to manipulate the user interface on the display (e.g., 450 in FIG. 4B) of the multifunction device when the touch-sensitive surface is separate from the display. It should be understood that similar methods are, optionally, used for other user interfaces described herein.

Additionally, while the following examples are given primarily with reference to finger inputs (e.g., finger contacts, finger tap gestures, finger swipe gestures), it should be understood that, in some embodiments, one or more of the finger inputs are replaced with input from another input device (e.g., a mouse based input or stylus input). For example, a swipe gesture is, optionally, replaced with a mouse click (e.g., instead of a contact) followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). As another example, a tap gesture is, optionally, replaced with a mouse click while the cursor is located over the location of the tap gesture (e.g., instead of detection of the contact followed by ceasing to detect the contact). Similarly, when multiple user inputs are simultaneously detected, it should be understood that multiple computer mice are, optionally, used simultaneously, or a mouse and finger contacts are, optionally, used simultaneously.

As used herein, the term “focus selector” refers to an input element that indicates a current part of a user interface with which a user is interacting. In some implementations that include a cursor or other location marker, the cursor acts as a “focus selector,” so that when an input (e.g., a press input) is detected on a touch-sensitive surface (e.g., touchpad 355 in FIG. 3 or touch-sensitive surface 451 in FIG. 4B) while the cursor is over a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations that include a touch-screen display (e.g., touch-sensitive display system 112 in FIG. 1A or touch screen 112 in FIG. 4A) that enables direct interaction with user interface elements on the touch-screen display, a detected contact on the touch-screen acts as a “focus selector,” so that when an input (e.g., a press input by the contact) is detected on the touch-screen display at a location of a particular user interface element (e.g., a button, window, slider or other user interface element), the particular user interface element is adjusted in accordance with the detected input. In some implementations focus is moved from one region of a user interface to another region of the user interface without corresponding movement of a cursor or movement of a contact on a touch-screen display (e.g., by using a tab key or arrow keys to move focus from one button to another button); in these implementations, the focus selector moves in accordance with movement of focus between different regions of the user interface. Without regard to the specific form taken by the focus selector, the focus selector is generally the user interface element (or contact on a touch-screen display) that is controlled by the user so as to communicate the user's intended interaction with the user interface (e.g., by indicating, to the device, the element of the user interface with which the user is intending to interact). For example, the location of a focus selector (e.g., a cursor, a contact or a selection box) over a respective button while a press input is detected on the touch-sensitive surface (e.g., a touchpad or touch screen) will indicate that the user is intending to activate the respective button (as opposed to other user interface elements shown on a display of the device).

The user interface figures described below include various intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to one or more intensity thresholds (e.g., a contact detection intensity threshold IT₀, a light press intensity threshold IT_(L), a deep press intensity threshold IT_(D), and/or one or more other intensity thresholds). This intensity diagram is typically not part of the displayed user interface, but is provided to aid in the interpretation of the figures. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform operations that are different from operations typically associated with clicking a button of a physical mouse or a trackpad. In some embodiments, when a contact is detected with an intensity below the light press intensity threshold (e.g., and above a nominal contact-detection intensity threshold IT₀ below which the contact is no longer detected), the device will move a focus selector in accordance with movement of the contact on the touch-sensitive surface without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally, unless otherwise stated, these intensity thresholds are consistent between different sets of user interface figures.

An increase of intensity of the contact from an intensity below the light press intensity threshold IT_(L) to an intensity between the light press intensity threshold IT_(L) and the deep press intensity threshold IT_(D) is sometimes referred to as a “light press” input. An increase of intensity of the contact from an intensity below the deep press intensity threshold IT_(D) to an intensity above the deep press intensity threshold IT_(D) is sometimes referred to as a “deep press” input. An increase of intensity of the contact from an intensity below the contact-detection intensity threshold IT₀ to an intensity between the contact-detection intensity threshold IT₀ and the light press intensity threshold IT_(L) is sometimes referred to as detecting the contact on the touch-surface. A decrease of intensity of the contact from an intensity above the contact-detection intensity threshold IT₀ to an intensity below the contact intensity threshold IT₀ is sometimes referred to as detecting liftoff of the contact from the touch-surface. In some embodiments IT₀ is zero. In some embodiments IT₀ is greater than zero. In some illustrations a shaded circle or oval is used to represent intensity of a contact on the touch-sensitive surface. In some illustrations a circle or oval without shading is used represent a respective contact on the touch-sensitive surface without specifying the intensity of the respective contact.

In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a respective press input or in response to detecting the respective press input performed with a respective contact (or a plurality of contacts), where the respective press input is detected based at least in part on detecting an increase in intensity of the contact (or plurality of contacts) above a press-input intensity threshold. In some embodiments, the respective operation is performed in response to detecting the increase in intensity of the respective contact above the press-input intensity threshold (e.g., a “down stroke” of the respective press input). In some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the press-input threshold (e.g., an “up stroke” of the respective press input).

In some embodiments, the device employs intensity hysteresis to avoid accidental inputs sometimes termed “jitter,” where the device defines or selects a hysteresis intensity threshold with a predefined relationship to the press-input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press-input intensity threshold or the hysteresis intensity threshold is 75%, 90% or some reasonable proportion of the press-input intensity threshold). Thus, in some embodiments, the press input includes an increase in intensity of the respective contact above the press-input intensity threshold and a subsequent decrease in intensity of the contact below the hysteresis intensity threshold that corresponds to the press-input intensity threshold, and the respective operation is performed in response to detecting the subsequent decrease in intensity of the respective contact below the hysteresis intensity threshold (e.g., an “up stroke” of the respective press input). Similarly, in some embodiments, the press input is detected only when the device detects an increase in intensity of the contact from an intensity at or below the hysteresis intensity threshold to an intensity at or above the press-input intensity threshold and, optionally, a subsequent decrease in intensity of the contact to an intensity at or below the hysteresis intensity, and the respective operation is performed in response to detecting the press input (e.g., the increase in intensity of the contact or the decrease in intensity of the contact, depending on the circumstances).

For ease of explanation, the description of operations performed in response to a press input associated with a press-input intensity threshold or in response to a gesture including the press input are, optionally, triggered in response to detecting either: an increase in intensity of a contact above the press-input intensity threshold, an increase in intensity of a contact from an intensity below the hysteresis intensity threshold to an intensity above the press-input intensity threshold, a decrease in intensity of the contact below the press-input intensity threshold, and/or a decrease in intensity of the contact below the hysteresis intensity threshold corresponding to the press-input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting a decrease in intensity of a contact below the press-input intensity threshold, the operation is, optionally, performed in response to detecting a decrease in intensity of the contact below a hysteresis intensity threshold corresponding to, and lower than, the press-input intensity threshold.

User Interfaces and Associated Processes Selecting User Interface Objects

Many electronic devices have graphical user interfaces that display user interface objects such as thumbnails, icons, folders, and thumb/handles in scrubbers and slider bar. Often, a user of an electronic device will want to select and move user interface objects on a display. For example, a user will want to rearrange desktop items on a desktop of a user interface. As another example, a user may want to rearrange the order of applications, or “apps” displayed on the display of a portable multifunction device (such as a smart-phone or the like). As yet another example, a user may want to move the handle of the volume bar (a handle being a type of user interface object) to change the volume produced by the media player. Some methods of selecting user interface objects on electronic devices with touch-sensitive surfaces typically require a new input to individually select a user interface object (e.g., a mouse click or a tap and drag input). Moreover, once one user interface object is selected, selection of a second user interface object (e.g., another desktop item) requires a separate input (e.g., a different tap and drag gesture with a different contact). The problem with such methods is that they fail to provide a convenient way for users to select a user interface object during the course of a continuous contact with a touch-sensitive surface. The embodiments described below provide an effective, efficient method for an electronic device with a touch-sensitive surface to select multiple objects by determining whether or not to select a user interface object, based on an intensity of a contact with the touch-sensitive surface.

FIGS. 5A-5AA illustrate exemplary user interfaces for selecting user interface objects in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 6A-6E. FIGS. 5A-5AA include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a predefined intensity threshold (e.g., light press intensity threshold “IT_(L)”). In some embodiments, operations similar to those described below with reference to the light press intensity threshold IT_(L) are performed with reference to a deep press intensity threshold IT_(D).

In some embodiments, the device is portable multifunction device 100, the display is touch-sensitive display system 112, and the touch-sensitive surface includes tactile output generators 167 on the display (FIG. 1A). For convenience of explanation, the embodiments described with reference to FIGS. 5A-5AA and FIG. 6A-6E will be discussed with reference to display 450 and a separate touch-sensitive surface 451, however analogous operations are, optionally, performed on a device with a touch-sensitive display system 112 in response to detecting the contacts described in FIGS. 5A-5AA on the touch-sensitive display system 112 while displaying the user interfaces shown in FIGS. 5A-5AA on the touch-sensitive display system 112; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112, in place of cursor 17108, cursor 17132 or cursor 17140.

FIGS. 5A-5AA illustrate exemplary user interfaces for selecting user interface objects in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 6A-6E.

FIGS. 5A-5E illustrate an example of selecting a user interface object in accordance with some embodiments. User interface 17100 is displayed on display 450 and includes user interface objects (e.g., thumbnails 17102, dock 17104, taskbar 17105) as well as a focus selector (e.g., cursor 17108).

FIG. 5B illustrates an example of a user interface in which a contact 17110 (e.g., a press input) is detected on touch-sensitive surface 451. Contact 17110 is detected on the touch-sensitive surface (contact 17110 has an intensity on the touch-sensitive surface 451, sometimes referred to simply as “an intensity of contact” or “contact intensity”). Contact 17110 in FIG. 5B controls the position of cursor 17108. For example, movement of contact 17110 across touch-sensitive surface 451 (illustrated by the arrow attached to contact 17110) causes cursor 17108 to move toward, or in some cases to, a location of thumbnail 17102-1 on display 450.

FIGS. 5B-5C further illustrate an example of moving a focus selector (e.g., cursor 17108) over a user interface object. FIG. 5C follows from FIG. 5B in the sense that detection of movement of contact 17110 on touch-sensitive surface 451 from the location of contact 17110 in FIG. 5B to the location of contact 17110 in FIG. 5C causes the device to move cursor 17108 over thumbnail 17102-1. It should be appreciated that the location of thumbnail 17102-1 is, optionally, defined as a point (e.g., a corner of the thumbnail, a centroid or geometric center), or by a non-zero area, such as any location within the boundary of thumbnail 17102 or a hidden hit region for thumbnail 17102-1. In some embodiments, the hidden hit region is larger than thumbnail 17102-1. In some embodiments, the hidden hit region is “shifted” relative to the boundary of thumbnail 17102-1. Accordingly, in some embodiments, cursor 17108 is considered “over” thumbnail 17102-1 whenever cursor 17108 is displayed within the boundary defining the location of thumbnail 17102-1. The location of other user interface objects is, optionally, defined in a similar manner.

FIGS. 5C-5D illustrate an example of selecting a user interface object based on intensity of contact 17110 while the focus selector (in this example, cursor 17108) is at the location of thumbnail 17102-1. In this example, a light press input (e.g., an increase in intensity of contact 17108 from an intensity below IT_(L) in FIG. 5C to an intensity above IT_(L) in FIG. 5D) is detected while cursor 17108 is over thumbnail 17102-1. FIG. 5D illustrates an example of a response of the device to detecting a light press while cursor 17108 is over thumbnail 17102-1. In response to detecting the light press input, the device selects thumbnail 17102-1, as shown in FIG. 5D. In some embodiments, the selection of thumbnail 17102-1 is indicated by displaying a thumbnail representation (e.g., TNR 17116-1, FIG. 5E) at the original location thumbnail 17102-1. In some embodiments, a thumbnail representation is not displayed. In some embodiments, the device alters the appearance of thumbnail 17102-1 to indicate that it has been selected (e.g., the displayed thumbnail is highlighted). In the example shown in FIG. 5E, thumbnail 17102-1 is now “attached” to cursor 17108 and will move on the display, along with cursor 17108, in response to subsequent detection of movement of contact 17110 until the thumbnail is dropped.

FIG. 5E illustrates an example of a response to movement of contact 17110 after thumbnail 17102-1 is selected. In response to movement of contact 17110 across touch-sensitive surface 451 (e.g., from the location of contact 17110 in FIG. 5D to the location of contact 17110 in FIG. 5E), cursor 17108 is moved and thumbnail 17102-1 is moved in a corresponding manner (e.g., thumbnail 17102-1 is moved so that it remains proximate to cursor 17108). In some embodiments, after selection of user interface object 17102-1, the intensity of contact 17110 does not need to be maintained above the predefined intensity threshold. For example, the intensity of contact 17110, as shown in FIG. 5E, is below light press intensity threshold IT_(L), however, user interface object 17102-1 remains selected. In some embodiments, the intensity of contact 17110 remains above the light press intensity threshold with the same effect.

FIGS. 5A-5B and 5F-5G illustrate an example of forgoing selection of a user interface object in accordance with some embodiments. FIGS. 5A and 5B again demonstrate aspects of the method previous described with references to those figures, e.g., detection of a contact, movement of the contact and corresponding movement of the focus selector, and the like. In this example, however, contact 17110 as shown in FIG. 5F, remains below the light press intensity threshold IT_(L) while cursor 17108 is over user interface object 17102-1. As a result, the device forgoes selection of thumbnail 17102-1. This response by the device provides an intuitive way for the user to drag cursor 17108 over thumbnail 17102-1 (e.g., “mouse-over”) without selecting the thumbnail because the user has not increased the intensity of contact 17110 above IT_(L). The user can subsequently move the cursor to a different location (e.g., the location of cursor 17108 in FIG. 5G) without dragging thumbnail 17102-1 along with it.

FIGS. 5A-5B and 5H-5J illustrate an example of embodiments in which selection of a user interface object is based on a change in the intensity of a contact relative to an initial intensity of the contact. The examples illustrated in these are different from the embodiments described above with reference to FIGS. 5A-5G, in which a particular intensity value (e.g., IT_(L)) is used as an intensity threshold that is used in determining whether to select, or forgo selecting, a user interface object. FIGS. 5A and 5B illustrate positioning cursor 17108 over thumbnail 17102-1 as described previously. FIG. 5G includes a graph showing the intensity of contact 17110 versus time during the period that cursor 17108 is over thumbnail 17102-1. The device selects a baseline intensity for comparison, labeled I0. It should be appreciated that I0 is, optionally, determined in any number of ways. For example, in some embodiments, I0 is the intensity of contact at the moment when cursor 17108 is first detected “over” thumbnail 17102-1, where the term “over” should be interpreted as previously described. In some embodiments, I0 is an average contact intensity of contact 17110, starting from the beginning of the contact. In still alternative embodiments, I0 is a “smart” value, meaning that the value is adapted to a particular user (e.g., I0 is higher for users who tend to press harder during normal use). FIG. 5H shows an example of contact 17110 having an intensity that exceeds, at a particular time T0, a predefined threshold for a change in contact intensity relative to I0. In this example, the predefined threshold for a change in contact intensity relative to I0 is 50%. Thus, in this example, when the contact intensity reaches I0+50% of I0, (or, equivalently, I[T0]=1.5×I0) predefined selection criteria are met and thumbnail 17102-1 is selected. FIG. 5I illustrates selection of thumbnail 17102-1, subsequent to (e.g., at a time T0+Δ) and in response to predefined selection criteria being met as described with reference to FIG. 5H. FIGS. 5I-5J illustrate movement of cursor 17108 and thumbnail representation 17116-1 following selection of thumbnail 17102-1 in response to detecting movement of contact 17110 (e.g., from the location of contact 17110 in FIG. 5I to the location of contact 17110 in FIG. 5J). These operations are analogous to those discussed with reference to FIG. 5E.

FIGS. 5A-5B and FIGS. 5K-5L illustrate an example of embodiments in which forgoing selection of a user interface object is based on a change in the intensity of a contact relative to an initial intensity of the contact, in accordance with some embodiments. In FIG. 5K, cursor 17108 is positioned over thumbnail 17102-1 as described previously with reference to FIGS. 5A-5B. An initial contact intensity I0 is determined as described with references to FIG. 5H. In this example, however, the contact intensity does not exceed the predefined threshold for change in contact intensity while cursor 17108 is at position over thumbnail 17102-1. As a result, the device forgoes selection of thumbnail 17102-1. Detection of subsequent movement of contact 17110, shown in FIG. 5L, results in movement of cursor (e.g., from the position of cursor 17108 in FIG. 5K to the position of cursor 17108 in FIG. 5L) without corresponding movement of thumbnail 17102-1.

FIGS. 5M-5P illustrate selection of a second user interface object (e.g., thumbnail 17102-2) in accordance with some embodiments. After selection of thumbnail 17102-1 (for example, as shown in FIG. 5D) the device detects movement of contact 17110 in FIG. 5M and, in response, moves cursor 17108 from its previous position in FIG. 5M to a new position that is over thumbnail 17102-2 in FIG. 5N. In response to detecting a light press input while cursor 17108 is over thumbnail 17102-2, as shown in FIGS. 5N-5O where the intensity of contact 17110 increases from an intensity below IT_(L) to an intensity above IT_(L), the device selects thumbnail 17102-2 without deselecting or dropping thumbnail 17102-1. In FIG. 5P, the device detects movement of contact 17110 (e.g., from the position of contact 17110 in FIG. 5O to the position of contact 17110 in FIG. 5P) and, in response to detecting the movement of contact 17110 in FIG. 5P, the device moves cursor 17108 and both of the selected thumbnails 17102-1 and 17102-2, as shown in FIG. 5P.

As shown in FIG. 5P, after thumbnails 17102-1 and 17102-2 have been selected and moved in accordance with movement of cursor 17108, the device displays respective residual images 17116-1 and 17116-2 that correspond to the respective thumbnails. In some embodiments, detecting a light press input (e.g., an increase in intensity of contact 17110 from an intensity below IT_(L) to an intensity above IT_(L)) while cursor 17108 is over one of the residual images would cause the device to deselect the corresponding thumbnail. For example, in FIG. 5P, if the device detected a light press input after moving cursor 17108 over residual image 17116-2, the device would deselect thumbnail 17102-2. Similarly, in FIG. 5P, if the device detected a light press input after moving cursor 17108 over residual image 17116-1, the device would deselect thumbnail 17102-1.

FIGS. 5M-5N and 5Q-5R illustrate examples of forgoing selection of a second user interface object (e.g., thumbnail 17102-2), while maintaining selection of a first user interface object (e.g., thumbnail 17102-1). After selection of thumbnail 17102-1 (for example, as shown in FIG. 5D) the device detects movement of contact 17110 in FIG. 5M and, in response moves cursor 17108 from its previous position shown in FIG. 5M to a new position that is over thumbnail as shown in FIG. 5N. In FIG. 5Q, the intensity of contact 17110 remains below the light press threshold during the period of time in which the cursor 17108 is over thumbnail 17102-2. As a result, the device forgoes selection of thumbnail 17102-2 and detection of movement of contact 17110 results in movement of the cursor 17108 accompanied by Thumbnail 17102-1, and not by thumbnail 17102-2 or a representation of thumbnail 17102-2, as shown in FIG. 5R. In some embodiments, selecting, or forgoing selection of, a second user interface object is based on a change in the intensity of contact relative to an initial intensity of contact, as previously described, rather than a “fixed” or “absolute” intensity threshold.

In some circumstances, movement of a particular user interface object is naturally constrained to one dimension. For example, volume sliders (which allow a user to graphically adjust the volume of, for example, speakers integrated into electronic device 300) and video scrubbers (which allow users to graphically “fast-forward” or “rewind” a digital video clip, also sometimes called a video scrub bar) are constrained to up and down or, alternatively, forward and back directions. FIGS. 5S-5AA illustrate several examples of selecting a user interface object, or forgoing selection of a user interface object, that is constrained to one dimensions.

FIG. 5S illustrates a user interface with a media player 17130. Media player 17130 includes a video scrubber 17134. Video scrubber 17134 includes a handle 17136 that indicates progress of a video clip. For example, as the video clip progresses, handle 17136 moves to the right. In some embodiments, a user can “click-and-drag” handle 17136 to the left (thereby “rewinding”) or to the right (thereby “fast-forwarding”). However, in some user interfaces, subsequent motion of cursor 17132 away from the scrubber results in handle 17136 being deselected or dropped. In some embodiments described herein, a determination is made as to whether or not to select handle 17136 based on the intensity of contact while cursor 17132 is over handle 17136. When handle 17136 is selected, handle 17136 remains selected despite movement of cursor 17132 away from the scrubber, as described below. Additionally, in some user interfaces, a respective user interface object is only selected when a contact is initially detected in conjunction with detecting a focus selector over the respective user interface object (e.g., if a contact is detected on a touch-screen display at a position remote from a thumb on a slider, the thumb is not selected even if the contact moves over the thumb). Thus, it would be advantageous to be able to select and maintain selection of a user interface object that is constrained to a predefined path based on intensity of a contact rather than initial position of a focus selector on a touch-sensitive surface.

FIGS. 5S-5T illustrate moving a focus selector (e.g., cursor 17132) across display 450 in response to detecting movement of contact 17138 across the touch-sensitive surface 451. As shown in FIG. 5S before detecting the movement of contact 17138, cursor 17132 is at a position remote from handle 17136, and the device moves cursor 17132 over handle 17136, as shown in FIG. 5T. FIGS. 5T-5U illustrate detecting a light press input including detecting an increase in the intensity of contact 17138 from an intensity below IT_(L) to an intensity above IT_(L). FIGS. 5U-5V illustrate movement of contact 17138 that corresponds to movement of cursor 17132 to a new position shown in FIG. 5V. Although cursor 17132 is allowed to move freely within the two dimensions of the display in FIGS. 5S-5V, handle 17136 is constrained to an allowed direction defined by the scrubber 17134. As a result, handle 17136 follows the projection (or the component of) of the movement of cursor 17132 on the display in the allowed direction along the scrubber 17134.

FIGS. 5W-5AA illustrate an example of selection and movement of a user interface objects constrained to one dimension. However, in this example, the user interface objects (in this case icons in an icon bar) are constrained to visual discrete locations within their one dimensional range of motion. For instance, the icons in the icon bar are ordered from left-to-right and are consistently spaced. A user, therefore, is not permitted to randomly position icons within the icon bar, but can swap the location of two icons. In FIG. 5W, the device detects contact 17142 on touch-sensitive surface 451 and detects movement of the contact (e.g., from the position of contact 17142 in FIG. 5W to the position of contact 17142 in FIG. 5X) and in response to detecting the movement of contact 17142, the device moves cursor 17140. In FIGS. 5W-5X, the device moves the cursor 17140 from a position remote from folder A in FIG. 5W to a position over folder A in FIG. 5X. In FIGS. 5X-5Y, the device detects a light press input including detecting an increase in intensity of contact 17142 from an intensity below IT_(L) to an intensity above IT_(L) and in response, the device selects Folder A. In response to detecting subsequent movement of contact 17142 shown in FIG. 5Z-5AA, the device moves cursor 17140 and re-orders the icons in the task bar, as shown in FIGS. 5Z-5AA. For example, in some embodiments, the final position of Folder A is determined using the projection of cursor movement along the allowed direction and then rounded to determine the new location among the discrete locations available to Folder A. When a determination is made that Folder A should move, for example, one place to the right of its current location, the device swaps the location of Folder A and the icon to its right. For example, FIG. 5Z illustrates swapping the location of Folder A and Folder B. Similarly, FIG. 5AA illustrates an example of further swapping Folder A with the music icon in response to additional movement of cursor 17140 that includes a component corresponding to movement of cursor 17140 to the right on display 450.

FIGS. 6A-6E are flow diagrams illustrating a method 17200 of determining whether to select a user interface object or forgo selecting a user interface object when a focus selector that corresponds to a contact that is already detected on the touch-sensitive surface passes over the user interface object, based on an intensity of the contact, on the touch-sensitive surface, while the focus selector is over the user interface object, in accordance with some embodiments. Method 17200 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 17200 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, method 17200 provides an intuitive way to select a user interface object. The method reduces the cognitive burden on a user when selecting a user interface object, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, method 17200 enables a user to select user interface object faster and more efficiently conserves power and increases the time between battery charges.

The device displays (17202) a first user interface object at a first location on the display, for example, thumbnail 17102-1 as described with reference to FIG. 5A. The device detects (17204) a contact (e.g., a finger contact) with a touch-sensitive surface, such as contact 17110 described with reference to 171B. The device detects (17206) first movement of the contact across the touch-sensitive surface that corresponds to movement of a focus selector toward the first location (e.g., to the first location). The first location is, optionally, a point or a region with a non-zero area, such as a hidden hit region for the first user interface object. In response to detecting the first movement of the contact (17208), the device moves the focus selector (17210) from a location remote from the first user interface object to the first location. For example, in FIG. 5B, cursor 17108 starts at an initial location, and in response to detecting movement of contact 17110 in FIG. 5C of the device moves cursor 17108 to a new location over thumbnail 17102-1.

The device also determines (17212) an intensity of the contact on the touch-sensitive surface while the focus selector is at the first location. After detecting the first movement of the contact, the device detects (17214) second movement of the contact across the touch-sensitive surface that corresponds to movement of the focus selector away from the first location. For example in FIGS. 5E, 5G, 5J and 5L the device detects movement of contact 17110 and, in response to detecting the movement of 17110 the device moves cursor 17108 away from the location corresponding to thumbnail 17102-1. In response to detecting the second movement of the contact (17216), the device determines (17218) whether the contact meets selection criteria for the first user interface object. The selection criteria for the first user interface object include that the contact meets a predefined intensity threshold while the focus selector is at the first location. FIGS. 5C-5E and FIGS. 5H-5J illustrate examples where the contact meets the selection criteria while the focus selector (e.g., cursor 17108) is over the first user interface object (e.g., thumbnail 17102-1). FIGS. 5F-5G and FIGS. 5K-5L illustrate examples where the contact does not meet the selection criteria while the focus selector (e.g., cursor 17108) is over the first user interface object (e.g., thumbnail 17102-1).

In some embodiments, the predefined intensity threshold is based (17220) at least in part on a magnitude of intensity of the contact (e.g., if the intensity of the contact is above a predefined amount of pressure that is greater than zero, then the device picks up the first user interface object). For example, FIGS. 5C-5E show an example in which the predefined intensity threshold is the light press intensity threshold (e.g., IT_(L)) and the predefined selection criteria are met because an intensity of contact 17110 is above the light press intensity threshold while cursor 17108 is over thumbnail 17102-1. On the other hand, the predefined selection criteria are not met in FIGS. 5F-5G, because contact 17110 does not have an intensity above the light press intensity threshold (e.g., IT_(L)) while cursor 17108 is over thumbnail 17102-1. In some embodiments, the predefined intensity threshold is based (17222) at least in part on an amount of change in intensity of the contact (e.g., if the intensity of the contact increases by 50%, then pick up the first user interface object). For example, FIGS. 5H-5J show an example in which the predefined selection criteria are met because an intensity of contact 17110 increases from a baseline intensity I0 by more than 50% while cursor 17108 is over thumbnail 17102-1. On the other hand, the predefined selection criteria are not met in FIGS. 5K-5L, because contact 17110 does not increase from a baseline intensity I0 by more than 50% while cursor 17108 is over thumbnail 17102-1.

In accordance with the determination that the contact meets (17224—Yes) selection criteria for the first user interface object, the device moves the focus selector and the first user interface object as described in greater detail below. In contrast, in accordance with a determination that the contact does not (17224—No) meet the selection criteria for the first user interface object, the device moves (17226) the focus selector in accordance with the second movement of the contact without moving the first user interface object (e.g., the device forgoes selecting/picking-up the first user interface object). For example, FIG. 5F shows cursor 17108 at respective location over thumbnail 17102-1, while FIG. 5G shows movement of contact 17110 along with corresponding movement of the focus selector to a new location away from thumbnail 17102-1. However, because the selection criteria for thumbnail 17102-1 were not met prior to detecting movement of contact 17110, thumbnail 17102-1 remains at the first location in FIG. 5G.

In accordance with the determination that the contact meets (17224—Yes) selection criteria for the first user interface object, the device moves (17228) the focus selector and the first user interface object away from the first location in accordance with the second movement of the contact (e.g., the device selects/picks-up the first user interface object, as illustrated in FIGS. 5E and 5J, where thumbnail 17102-1 is moved in accordance with movement of cursor 17108).

In some embodiments, movement of the first user interface object (such as a thumb or handle in a scrubber or a slider) is constrained (17230) to a predefined path in the user interface, and moving the first user interface object includes moving the first user interface object along the predefined path in accordance with a component of motion of the focus selector that corresponds to an allowed direction of motion along the predefined path. Examples of these embodiments are illustrated in the user interfaces shown in FIGS. 5S-5AA. Alternatively, in some embodiments, the first user interface object has a two-dimensional range of motion (17232), and moving the first user interface object includes moving the first user interface object to a location at or adjacent to the focus selector on the display. For example, the first user interface object is a document icon that can be moved laterally on the display in a two dimensional plane and is not constrained to a predefined path. Similar examples are illustrated in the user interfaces shown in FIGS. 5A-5R. In some embodiments, the device displays (17234) a second user interface object at a second location on the display while the first user interface object is displayed on the display (e.g., thumbnail 17102-2 in FIG. 5A). While continuing to detect (17236) the contact and moving the first user interface object in accordance with movement of the focus selector, after detecting the second movement of the contact, the device detects (17238) third movement of the contact across the touch-sensitive surface that corresponds to movement of the focus selector toward the second location (e.g., to the second location). In response to detecting the third movement of the contact (17240), the device moves (17242) the focus selector from a location remote from the second user interface object (e.g., from the first location or a location proximate to the first location) to the second location. In some embodiments, the second location is a point or a region with a non-zero area, such as a hidden hit region for the second user interface object. For example, in FIGS. 5N and 5Q, the device detects movement of contact 17110 and in response to detecting movement of contact 17110 downward on touch-sensitive surface 451, the device moves cursor 17108 over a second user interface object (e.g., thumbnail 17102-2).

In response to detecting third movement of the contact, the device also determines (17244) an intensity of contact on the touch-sensitive surface while the focus selector is at the second location. After detecting the third movement of the contact, the device detects (17246) fourth movement of the contact across the touch-sensitive surface that corresponds to movement of the focus selector away from the second location. For example, in FIGS. 5P and 5R, the device detects movement of contact 17110 and in response to detecting movement of contact 17110 to the left on touch-sensitive surface 451, the device moves cursor 17108 away from the location occupied by a second user interface object (e.g., thumbnail 17102-2) before detecting the third movement or the fourth movement.

In some embodiments, after detecting the first movement and before detecting the fourth movement, the device detects (17247) a decrease in intensity of the contact below the predefined intensity threshold, and after detecting the decrease in intensity of the contact below the predefined intensity threshold, the device continues to move the first user interface object in accordance with movement of the focus selector (e.g., in FIG. 5Q, contact 17110 has an intensity below IT_(L)). For example, after “picking up” the first user interface object, the user can lower the intensity of the contact without “dropping” the first user interface object, so that the user will be able to “pick up” additional user interface objects (e.g., the second user interface object) by increasing the intensity of the contact above the predefined intensity threshold again over each additional user interface object. If the user has picked up several user interface objects (e.g., the first user interface object and the second user interface object), the user can lower the intensity of the contact without “dropping” the any of the user interface objects, so that the user will be able to “pick up” additional user interface objects (e.g., the second user interface object) by increasing the intensity of the contact above the predefined intensity threshold again over each additional user interface object.

In response to detecting (17248) the fourth movement of the contact, the device determines whether the contact meets selection criteria for the second user interface object. The selection criteria for the second user interface object include that the contact meets the predefined intensity threshold while the focus selector is at the second location.

In accordance with a determination that the contact does not (17252—No) meet the selection criteria for the second user interface object, the device moves (17254) the focus selector and the first user interface object in accordance with the fourth movement of the contact without moving the second user interface object (e.g., the device forgoes selection/fails to pick-up the second user interface object, as illustrated in FIG. 5R, where thumbnail 17102-2 is not moved in accordance with movement of cursor 17108). In some embodiments, when a first user interface object is already selected and the device detects an increase in intensity of the contact while the focus selector is over the second object, the second object is picked up in addition to the first object. As such, the user can select and move multiple objects with a single contact by moving the focus selector over a plurality of different user interface objects and performing a press gesture that includes increasing the intensity of the contact above the predefined intensity threshold while the focus selector is over each of the user interface objects.

In accordance with a determination that the contact meets (17252—Yes) selection criteria for the second user interface object, the device moves (17256) the focus selector, the first user interface object, and the second user interface object away from the second location in accordance with the fourth movement of the contact (e.g., the device selects/picks-up the second user interface object and moves the second user interface object along with the first user interface object, as illustrated in FIG. 5P, where thumbnail 17102-2 is moved in accordance with movement of cursor 17108). In some embodiments, after detecting the fourth movement of the contact, a representation of the first user interface object and a representation of the second user interface object are displayed (17258) moving on the display in accordance with movement of the focus selector (e.g., as illustrated in FIG. 5P). In some embodiments, after detecting the fourth movement of the contact, a representation of a group of objects corresponding to the first user interface object and the second user interface object are displayed (17260) moving on the display in accordance with movement of the focus selector.

It should be understood that the particular order in which the operations in FIGS. 6A-6E have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method 17200 described above with respect to FIGS. 6A-6E. For example, the contacts, user interface objects, intensity thresholds, and focus selectors described above with reference to method 17200 optionally have one or more of the characteristics of the contacts, user interface objects, intensity thresholds, and focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 7 shows a functional block diagram of an electronic device 17300 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 7 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 7, an electronic device 17300 includes a display unit 17302 configured to display a user interface that includes a first user interface object at a first location on the display unit, a touch-sensitive surface unit 17304 configured to detect contacts, one or more sensor units 17306 configured to detect intensity of contacts with the touch-sensitive surface unit 17304; and a processing unit 17308 coupled to the display unit 17302, the touch-sensitive surface unit 17304 and the one or more sensor units 17306. In some embodiments, the processing unit 17308 includes a display enabling unit 17310, a detecting unit 17312, a determining unit 17313, a selecting unit 17314, and a moving unit 17316.

Processing unit 17308 is configured to detect first movement of the contact (e.g., with the detecting unit 17312) across touch-sensitive surface unit 17304 that corresponds to movement of a focus selector toward the first location. In response to detecting the first movement of the contact, processing unit 17308 is configured to move (e.g., with the moving unit 17316) the focus selector from a location remote from the first user interface object to the first location, and determine (e.g., with the determining unit 17313) an intensity of the contact on touch-sensitive surface unit 17304 while the focus selector is at the first location. After detecting the first movement of the contact, processing unit 17308 is configured to detect second movement of the contact (e.g., with the detecting unit 17312) across the touch-sensitive surface unit 17304 that corresponds to movement of the focus selector away from the first location. In response to detecting the second movement of the contact, in accordance with a determination that the contact meets selection criteria for the first user interface object, where the selection criteria for the first user interface object include that the contact meets a predefined intensity threshold while the focus selector is at the first location, processing unit 17308 is configured to move (e.g., with the moving unit 17316) the focus selector and the first user interface object away from the first location in accordance with the second movement of the contact. In response to detecting the second movement of the contact, in accordance with a determination that the contact does not meet the selection criteria for the first user interface object, processing unit 17308 is configured to move (e.g., with the moving unit 17316) the focus selector in accordance with the second movement of the contact without moving the first user interface object.

In some embodiments, movement of the first user interface object is constrained to a predefined path in the user interface, and moving the first user interface object includes moving the first user interface object (e.g., with the moving unit 17316) along the predefined path in accordance with a component of motion of the focus selector that corresponds to an allowed direction of motion along the predefined path.

In some embodiments, the first user interface object has a two-dimensional range of motion, and moving the first user interface object includes moving the first user interface object (e.g., with the moving unit 17316) to a location at or adjacent to the focus selector on the display unit.

In some embodiments, the predefined intensity threshold is based at least in part on an amount of change in intensity of the contact.

In some embodiments, the predefined intensity threshold is based at least in part on a magnitude of intensity of the contact.

In some embodiments, a second user interface object is displayed on display unit 17302 at a second location on display unit 17302 while the first user interface object is displayed on display unit 17302, and processing unit 17308 is configured to, while continuing to detect the contact and moving the first user interface object in accordance with movement of the focus selector and after detecting the second movement of the contact, detect third movement of the contact (e.g., with the detecting unit 17312) across the touch-sensitive surface unit 17304 that corresponds to movement of the focus selector toward the second location (e.g., to the second location). In response to detecting the third movement of the contact, processing unit 17308 is configured to move (e.g., with the moving unit 17316) the focus selector from a location remote from the second user interface object to the second location, and determine (e.g., with the determining unit 17313) an intensity of the contact on the touch-sensitive surface unit 17304 while the focus selector is at the second location. After detecting the third movement of the contact, processing unit 17308 is configured to detect fourth movement of the contact (e.g., with the detecting unit 17312) across the touch-sensitive surface unit 17304 that corresponds to movement of the focus selector away from the second location. In response to detecting the fourth movement of the contact, in accordance with a determination that the contact meets selection criteria for the second user interface object, where the selection criteria for the second user interface object include that the contact meets the predefined intensity threshold while the focus selector is at the second location, processing unit 17308 is configured to move (e.g., with the moving unit 17316) the focus selector, the first user interface object, and the second user interface object away from the second location in accordance with the fourth movement of the contact. In response to detecting the fourth movement of the contact, in accordance with a determination that the contact does not meet the selection criteria for the second user interface object, processing unit 17308 is configured to move (e.g., with the moving unit 17316) the focus selector and the first user interface object in accordance with the fourth movement of the contact without moving the second user interface object.

In some embodiments, processing unit 17308 is further configured to, after detecting the fourth movement of the contact, display (e.g., with the display enabling unit 17310) a representation of the first user interface object and a representation of the second user interface object moving on the display unit in accordance with movement of the focus selector.

In some embodiments, processing unit 17308 is further configured to, after detecting the fourth movement of the contact, display (e.g., with the display enabling unit 17310) a representation of a group of objects corresponding to the first user interface object and the second user interface object moving on the display unit in accordance with movement of the focus selector.

In some embodiments, processing unit is further configured to, after detecting the first movement and before detecting the fourth movement detect a decrease in intensity of the contact (e.g., with the detecting unit 17312) below the predefined intensity threshold, and after detecting the decrease in intensity of the contact below the predefined intensity threshold, continuing to move (e.g., with the moving unit 17316) the first user interface object in accordance with movement of the focus selector.

The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A and 3) or application specific chips.

The operations described above with reference to FIGS. 6A-6E are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 7. For example, detection operations 17204 and 17212, moving operations 17210, 17226 and 17228, and determining operation 17212 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

Selecting User Interface Objects

Many electronic devices have graphical user interfaces that display user interface objects such as thumbnails, icons, folders, and thumb/handles in scrubbers and slider bar on a display. Such user interface items generally represent either a file or a directory (or sub-directory) corresponding to a collection of files. Often, a user of an electronic device will want to select and move user interface objects on the display. For example, a user will want to rearrange desktop items in a desktop environment/window system. As another example, a user may want to select several user interface objects and add the selected user interface object to a collection of user interface objects. Such operations occur, for example, while using a desktop environment (e.g., adding files to a folder), or between a desktop environment and an application (e.g., adding files from a desktop window to a play list in a media player), or within an application (e.g., selecting and dragging user interface items within a media player). As yet another example, a user may want to rearrange the order of thumbnails corresponding to applications, or “apps” displayed on the display of a portable multifunction device.

Some methods of selecting user interface objects on electronic devices with touch-sensitive surfaces typically require performing a distinct selection operation on each of a plurality of a user interface objects (e.g., activating a mouse button or placing a contact on a touch-sensitive surface) to individually select the user interface objects. Typically, in such embodiments, in order to perform a subsequent selection operation a user first ceases to select a previously selected object (e.g., a previously selected user interface object is deselected when the mouse button is deactivated or the contact is lifted off of the touch-sensitive surface). Thus, in these examples, selection of a second user interface object (e.g., another desktop item) requires a separate selection operation and consequently only one user interface object is selected at a time. Alternatively, some methods enable a user to select multiple user interface an area to select multiple user interface objects, however this method of selecting objects does not enable a user to a specific set of user interface objects from a group of user interface objects that are located in close proximity to each other. The embodiments described below provide a more efficient, intuitive method, implemented on an electronic device with a touch-sensitive surface, for determining whether to select a user interface object, or forgo selecting a user interface object, based on an intensity of a contact with the touch-sensitive surface. In some circumstances, multiple user interface objects are selected using a single, continuous contact or, alternative, multiple distinct contacts on the touch-sensitive surface.

FIGS. 8A-8DD illustrate exemplary user interfaces for selecting user interface objects in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 9A-9E. For figures that illustrate a contact with a touch-sensitive surface, an intensity diagram is included that shows the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including an alternative-mode intensity threshold (e.g., “IT_(D)”) and a selection intensity threshold (e.g., “IT_(L)”).

In some embodiments, the device is portable multifunction device 100, the display is touch-sensitive display system 112, and the touch-sensitive surface includes tactile output generators 167 on the display (FIG. 1A). For convenience of explanation, the embodiments described with reference to FIGS. 8A-8DD and FIGS. 9A-9E will be discussed with reference to display 450 and a separate touch-sensitive surface 451, however analogous operations are, optionally, performed on a device with a touch-sensitive display system 112 in response to detecting the contacts described in FIGS. 8A-8DD on the touch-sensitive display system 112 while displaying the user interfaces shown in FIGS. 8A-8DD on the touch-sensitive display system 112; in such embodiments, the focus selector is, optionally: a respective contact, a representative point corresponding to a contact (e.g., a centroid of a respective contact or a point associated with a respective contact), or a centroid of two or more contacts detected on the touch-sensitive display system 112, in place of cursor 17408.

FIG. 8A illustrates an exemplary user interface for selecting user interface objects in accordance with some embodiments. FIG. 8A illustrates an exemplary user interface 17400. User interface 17400 is displayed on display 450 and includes user interface objects (e.g., thumbnails 17402, folder 17404) as well as a focus selector (e.g., cursor 17408). FIG. 8B illustrates the device detecting movement of contact 17406 across touch-sensitive surface 451 and in response moving cursor 17408 across the display from a location remote from thumbnail 17402-1 in FIG. 8A to a location over thumbnail 17402-1 in FIG. 8B.

FIGS. 8B-8F illustrate an example user interface for selecting user interface objects in a first selection mode in accordance with some embodiments. At the outset of FIG. 8B, user interface 17400 is in a first selection mode (sometimes referred to as a “single object selection mode”) with properties described below. Furthermore, in FIGS. 8B-8F, contact 17406 represents a continuously detected (e.g., unbroken) contact with touch-sensitive surface 451, (e.g., the contact is continuously detected between the beginning of the first press input and the end of the second press input).

In some embodiments, contact 17406 controls the position of cursor 17408. For example, movement of contact 17406 across touch-sensitive surface 451 (illustrated by the arrow attached to contact 17406, FIG. 8B) causes cursor 17408 to move correspondingly toward, or in some cases to, a location of thumbnail 17402-1. It should be appreciated that the location of thumbnail 17402-1 is, optionally, defined as a point (e.g., a corner of the thumbnail, or the geometric center of mass), or by a non-zero area, such as any location within the boundary of thumbnail 17402 or a hidden hit region for thumbnail 17402-1. In some embodiments, the hidden hit region is larger than thumbnail 17402-1. In some implantations, the hidden hit region is “shifted” relative to the boundary of thumbnail 17402-1. Accordingly, in some embodiments, cursor 17408 is considered to be “over” thumbnail 17402-1 whenever cursor 17408 is displayed within the boundary defining the location of thumbnail 17402-1. Likewise, the location of other user interface objects is similarly defined. Regardless of the definition of the location of a user interface object, a press input detected while a focus selector is over a user interface object is sometimes referred to as a “press input on a respective user interface object,” or the like.

FIG. 8C shows detection of a “light press input,” e.g., a press input that corresponds to an increase in intensity of contact 17410 above a selection intensity threshold (e.g., “IT_(L)”) but below an alternative-mode intensity threshold (e.g., IT_(D)). Thumbnail 17402-1 is selected in response to the light press being detected while cursor 17408 is over thumbnail 17402-1, as shown in FIG. 8D. As shown in FIGS. 8D-8E, when the device is in a single object selection mode and intensity of contact 17406 drops below the IT_(L), thumbnail 17402-1 is deselected or “dropped.” Because thumbnail 17402-1 is no longer selected in FIG. 8E, subsequent movement of contact 17406 across touch-sensitive surface 451 moves cursor 17408 to the position without moving thumbnail 17402-1, as shown in FIG. 8F.

FIGS. 8G-8O illustrate an example user interface for selecting user interface objects in an alternative mode (sometimes referred to as a “select multiple objects” mode) in accordance with some embodiments. For ease of explanation, embodiments in FIGS. 8G-8O are described with reference to a continuous contact 17410. At the outset of FIG. 8G, user interface 17400 is in the selection mode, as described above. FIGS. 8G and 8H are analogous to FIGS. 8B and 8C, respectively, where the device moves cursor 17408 across the display from a location remote from thumbnail 17402-1 in FIG. 8A to a location over thumbnail 17402-1 in FIG. 8G in response to detecting movement of contact 17410 across touch-sensitive surface 451, with the difference that the press input in FIGS. 8G-8H corresponds to an increase in intensity of contact 17410 above an alternative-mode intensity threshold (e.g., “IT_(D)”). As a result, user interface 17400 enters an alternative mode (e.g., the select multiple objects mode). In some embodiments, when user interface 17400 is in the alternative mode, a subsequent decrease of intensity contact 17410 below IT_(L) does not result in thumbnail 17402-1 being dropped. For example, in FIG. 8I, thumbnail 17402-1 continues to be selected, even though the intensity of contact 17410 has decreased below IT_(L). Subsequent movement of contact 17410 across touch-sensitive surface 451 results in movement of cursor 17408 shown in FIG. 8J, accompanied by movement of thumbnail 17402-1. FIG. 8J also shows an example of the device displaying a residual image 17416 (e.g., 17416-1) of thumbnail 17402-1 on display 450.

FIGS. 8K-8L illustrate the device detecting subsequent movement contact 17410 on touch-sensitive surface 451, and, in response, moving cursor 17408 from a location remote from thumbnail 17402-2 as shown in FIG. 8K to a location over thumbnail 17402-2 as shown in FIG. 8L. In FIG. 8M, the device detects a subsequent (e.g., second) press input corresponding to an increase in intensity above the selection threshold (e.g., IT_(L)) while cursor 17408 is over a thumbnail 17402-2 and, in response, the device selects thumbnail 17402-2 without dropping thumbnail 17402-1. In some embodiments, the first press input and the second press input are made by a continuously detected (unbroken) contact on the touch-sensitive surface.

After selecting thumbnail 17402-2, while the device is in the multiple object selection mode, the device maintains selection of the selected thumbnails 17402-2 and 17402-1, even when the intensity of contact 17410 decreases below the selection intensity threshold (e.g., “IT_(L)”). In response to detecting movement of contact 17410 in FIG. 8O, the device moves the selected thumbnails away from the location previously occupied by thumbnail 17402-2, as shown in FIG. 8O. FIGS. 8N-8O are analogous to FIGS. 8I-8J with the difference that, because both thumbnail 17402-1 and thumbnail 17402-2 are selected, movement of cursor 17408 is accompanied by both thumbnails. A thumbnail residual 17416-2 is also displayed in FIG. 8O, corresponding to a residual of thumbnail 17402-2. Residual images 17416 have additional properties. In some embodiments, after a user interface object is selected and a residual image of the user interface object is displayed, a press input is detected on the residual image (e.g., contact 17410 increases from an intensity below IT_(L) to an intensity above IT_(L) while cursor 17408 is over a respective residual image). In some embodiments, in response to detecting the press input on a respective residual image, the user interface object corresponding to the respective residual image is deselected. For example, when thumbnails 17402-1 and 17402-2 are selected, a press input on residual image 17416-1 (e.g., an increase in intensity of contact 17410 from an intensity below IT_(L) to an intensity above IT_(L) while cursor 17408 is over residual image 17416-1) will cause the device to deselect thumbnail 17402-1 and maintain selection of thumbnail 17402-2. In some embodiments, an animation of thumbnail 17402-1 “flying back” and replacing residual image 17416-1 is performed.

In some embodiments, in response to detecting liftoff of a continuous contact (e.g., contact 17410, FIGS. 8G-8O) previously selected user interface objects (e.g., thumbnail 17402-1 and thumbnail 17402-2, FIG. 8O) are dropped in the user interface, as shown in FIG. 8P. In some embodiments, when previously selected user interface objects are dropped, the corresponding residual images (e.g., thumbnail residuals 17416) are no longer displayed and the user interface objects are displayed at a location proximate to a location of the cursor 17408 when the liftoff of contact 17410 was detected, as shown in FIG. 8P.

FIGS. 8G-8N and 8Q-8T illustrate selection of a third user interface object that is representative of a collection of user interface objects (e.g., a folder, sub-directory, photo album, playlist, etc.). Following FIGS. 8G-8N, which have already been described, FIG. 8Q illustrates movement of contact 17410 on touch-sensitive surface 451 that corresponds to movement of cursor 17408 to location over docs folder 17404, after thumbnails 17402-1 and 17402-2 have been selected. In response to detection of a light press input (e.g., an increase in intensity of contact 17410 from an intensity below IT_(L) to an intensity between IT_(L) and IT_(D), as shown in FIGS. 8Q-8R), the device selects folder 17404 without deselecting either of the thumbnails, as illustrated in FIG. 8R. FIGS. 8S-8T illustrate subsequent motion of the cursor accompanied by the selected thumbnails and of folder in response to detecting movement of contact 17410 on the touch-sensitive surface 451.

In contrast, FIGS. 8U-8X also follow FIGS. 8G-8N, but in this case, the detected press input is a deep press input (e.g., an increase in intensity of contact 17410 from an intensity below IT_(D) to an intensity above IT_(D), as shown in FIGS. 8U-8V). As a result, of detecting a deep press input instead of a light press input, the device displays a user interface (e.g., an open folder) with a region for adding thumbnails 17402-1 and 17402-2 to a collection of thumbnails. In FIG. 8W, thumbnails 17402-1 and 17402-1 are deselected in response to detecting liftoff of contact 17410, and, in FIG. 8W, the two thumbnails are added to the contents of the opened “docs” folder because cursor 17408 is over the representation of the docs folder 17404 when liftoff of contact 17410 is detected. The “docs” folder, for example, already contains other thumbnails, such as thumbnail 17402-4 and 17402-5. FIGS. 8W-8X illustrate an animation of thumbnails 17402-1 and 17402-2 moving from a location proximate to cursor 17408 to a location in an arrangement of thumbnail 17402 in the representation of docs folder. The exemplary user interfaces in FIGS. 8Q-8X therefore illustrate an example of an advantage of distinguishing between press inputs that reach different intensity thresholds (e.g., IT_(L) and IT_(D)), where the different press inputs can be used to provide an intuitive user interface that enables a user to either add a folder to a selection or open a folder to add selected items to the folder.

FIGS. 8Y-8DD illustrate embodiments of a user interface 17420 in which multiple, distinct contacts are used to selected user interface objects. For example, a first contact ceases to be detected prior to detecting a second contact. In some embodiments, the first contact and the second contact are made by the same finger at different times. In some embodiments (e.g., illustrated in FIGS. 8Y-8DD), the first press input is a “deep press” input that corresponds to an increase in intensity of a contact to an alternative-mode intensity threshold (e.g., “IT_(D)”) that is higher than a selection intensity threshold (e.g., “IT_(L)”), and in response to detecting the first press input, the device enters a “select multiple objects” mode where sequential press inputs that have an intensity at or above the selection intensity threshold (e.g., “IT_(L)”) cause the device to select multiple user interface objects simultaneously that correspond to the sequential press inputs.

FIG. 8Y illustrates a plurality of user interface objects (e.g., thumbnails 17418) representing media objects (e.g., pictures) in a media player displaying, for example, a photo album (e.g., “Family Photo Album”). Users of such a media player may wish to select several thumbnails at a time, for example, to add the selected pictures to a different album and/or delete unwanted pictures. FIG. 8Z shows a contact 17412 corresponding to a press input while cursor 17411 is over thumbnail 17418-1. The press input correspond to an increase in intensity of contact 17412 above an alternative-mode intensity threshold (e.g., “IT_(D)”). In response to detecting the press input, the device enters an alternate mode for selecting user interface objects and selects user interface object 17418-1.

FIG. 8AA shows liftoff of contact 17412 (e.g., contact 17412 is no longer detected on touch-sensitive surface 451). In FIG. 8AA, thumbnail 17418-1 remains selected after detecting liftoff, allowing additional user interface items to be selected. FIG. 8AA shows the device detecting movement of contact 17414 and, in response to detecting the movement of contact 17414, moving cursor 17411 from the location over thumbnail 17418-1 in FIG. 8Z to a position over thumbnail 17418-7 in FIG. 8AA. While cursor 17411 is over thumbnail 17418-7 in FIGS. 8AA-8BB, the device detects a press input corresponding to an increase in intensity of contact 17414, from an intensity below a selection intensity threshold (e.g., “IT_(L)”) to an intensity above the selection intensity threshold (e.g., “IT_(L)”), as shown in FIG. 8BB. In response to detecting the press input in FIG. 8BB, the device selects thumbnail 17418-7 in addition to thumbnail 17418-1.

FIG. 8CC shows detection of liftoff of contact 17414. In FIG. 8CC, both thumbnail 17418-1 and thumbnail 17418-7 remain selected in the illustrated embodiment, even though liftoff of contact 17414 has been detected. FIG. 8DD-8EE illustrate detection of a press input that does not correspond to a selectable user interface object (e.g., while the focus selector is at a location on the display that is outside of the plurality of user interface objects). In FIG. 8CC, the device detects movement of contact 17416 across touch-sensitive surface 451 and, in response moves cursor 17411 across the touch-sensitive surface to a location on the display that does not correspond to any of the plurality of thumbnails 17418. While cursor 17411 is at a location that does not correspond to any of the plurality of thumbnails 17418, the device detects a press input corresponding ton contact 17416 (e.g., an increase in intensity of contact 17416 from an intensity below IT_(L) to an intensity between IT_(L) and IT_(D)) and in response to detecting the press input in FIG. 8DD, the device cancels the selection and exits the “select multiple objects” or “alternative” mode.

FIGS. 9A-9E are flow diagrams illustrating a method 17500 of selecting user interface objects in accordance with some embodiments. The method 17500 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 17500 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 17500 provides an intuitive way to selecting user interface objects. The method reduces the cognitive burden on a user when selecting user interface objects, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to select user interface objects faster and more efficiently conserves power and increases the time between battery charges.

The device displays (17502) on a display, a plurality of user interface objects, including a first user interface object and a second user interface object (e.g., thumbnails 17402-1 and 17402-2, FIG. 8A and thumbnails 17418-1 and 17418-7 in FIG. 8Y). In some embodiments, the device is configured to detect (17504) a range of contact intensity values and compare the detected intensity values against a plurality of different intensity thresholds, and the plurality of different intensity thresholds includes an alternative-mode intensity threshold (e.g., “deep press” threshold IT_(D)) that is used by the device to transition from a first selection mode (e.g., a “single object selection” mode) to a second selection mode (e.g., a “multiple object selection” mode) and a selection intensity threshold (e.g., “light press” threshold IT_(L)) that is used by the device to differentiate between inputs that correspond to movement of the focus selector on the display (e.g., inputs with an intensity between IT₀ and IT_(L)) and inputs that correspond to selection of a user interface object at a location on the display at or near a location of the focus selector (e.g., inputs with an intensity between IT_(L) and IT_(D)), where the selection intensity threshold is different from (e.g., lower than) the alternative-mode intensity threshold. In some embodiments, during a normal mode of operation, when the device detects an increase in intensity of a contact above the selection intensity threshold while the focus selector is over a user interface object, the device selects the user interface object and when the device detects a decrease in intensity of the contact below the selection intensity threshold (or a predefined amount less than the selection intensity threshold) the device drops the object or performs an operation associated with activating the object (e.g., the device stops dragging an object that was being moved in accordance with movement of the focus selector or launches an application associated with the object if the object was not moved after detecting the increase in intensity of the contact).

While displaying the plurality of user interface objects, the device detects (17510) a first press input that corresponds to an increase in intensity of a contact above a first intensity threshold on the touch-sensitive surface while a focus selector is over the first user interface object. In response to detecting the first press input, the device selects (17512) the first user interface object, (e.g., selection of thumbnail 17402-1 in FIG. 8D and selection of thumbnail 17418-1 in FIG. 8Z).

After selecting the first user interface object (17514), the device detects (17516) a second press input that corresponds to an increase in intensity of a contact above a second intensity threshold on the touch-sensitive surface while the focus selector is over the second user interface object. In some embodiments, the first press input corresponds (17518) to a first contact on the touch-sensitive surface, and the second press input corresponds to a second contact on the touch-sensitive surface different from the first contact (e.g., the first contact ceases to be detected prior to detecting the second press input). In some embodiments, the first contact and the second contact are made by the same finger at different times, as shown in FIGS. 8Y-8DD. In some embodiments, the first press input is a “deep press” input that corresponds to an increase in intensity of a contact to an intensity threshold (e.g., “IT_(D)”) that is higher than a selection intensity threshold (e.g., “IT_(L)”), and in response to detecting the first press input, the device enters a “select multiple objects” mode where sequential press inputs that have an intensity at or above the selection intensity threshold cause the device to select multiple user interface objects simultaneously that correspond to the sequential press inputs. Alternatively, the first press input and the second press input are portions of a single gesture that includes (17520) a continuously detected contact on the touch-sensitive surface, as shown in FIGS. 8A-8X. For example, the contact is continuously detected between the beginning of the first press input and the end of the second press input. For example in FIGS. 8B-8F, the device detects various movements of contact 17406 across touch-sensitive surface 451 as well as various press inputs performed without detecting liftoff of contact 17406 from touch-sensitive surface 451. Similarly in FIGS. 8G-8X, the device detects various movements of contact 17410 across touch-sensitive surface 451 as well as various press inputs performed without detecting liftoff of contact 17410 from touch-sensitive surface 451. In contrast, in FIGS. 8Y-8DD, the device detects multiple, distinct contacts (e.g., 17412, 17414 and 17416) instead of a continuous contact when selecting multiple user interface objects.

In some embodiments, the first press input and the second press input are made by a continuously detected (unbroken) contact on the touch-sensitive surface. In some embodiments, the gesture includes (17522) an intermediate portion (e.g., movement of contact 17410 in FIGS. 8J-8L) between the first press input and the second press input that includes movement of the continuously detected contact corresponding to movement of the focus selector from the first user interface object to the second user interface object (e.g., while the focus selector is at the first user interface object, the user selects the first user interface object, then drags the focus selector across the display from the first user interface object to the second user interface object and selects the second user interface object as part of one continuous gesture).

Regardless of whether a single contact or multiple contacts are used, in some embodiments, as shown in FIGS. 8A-8X, and, separately, in FIGS. 8Y-8DD, the first intensity threshold is (17524) the alternative-mode intensity threshold (e.g., “IT_(D)”), and the second intensity threshold is the selection intensity threshold (e.g., “IT_(L)”). In some embodiments, the first press input is a “deep press” input that corresponds to an increase in intensity of a contact to an intensity threshold (e.g., “IT_(D)”) that is higher than a selection intensity threshold (e.g., “IT_(L)”), and in response to detecting the first press input, the device enters a “select multiple objects” mode where sequential press inputs that have an intensity at or above the light press intensity threshold cause the device to select multiple user interface objects simultaneously that correspond to the sequential press inputs, as shown in FIGS. 8G-8X. In the “select multiple objects” mode, the focus selector is moved sequentially over the user interface objects and, while the focus selector is over a respective user interface object, the intensity of the contact is increased above the selection intensity threshold in order to select the respective user interface object and then decreased below the selection intensity threshold while maintaining selection of the respective user interface object so that a next user interface object can be selected (e.g., a first deep press puts the device into a multiple-select mode and subsequent presses can be to a lower threshold, such as a light press input threshold).

Alternatively, in some embodiments, the first intensity threshold is (17526) the alternative-mode intensity threshold (e.g., “IT_(D)”), and the second intensity threshold is the alternative-mode intensity threshold (e.g., “IT_(D)”). Thus, in some embodiments, the second intensity threshold is the same as the first intensity threshold. For example, in some embodiments, the device enters the alternative mode in response to detecting a deep press input (e.g., an input including an increase in intensity of a contact from an intensity below IT_(D) to an intensity above IT_(D)) during selection of a first user interface object, and the device selects a second (or third, fourth, etc.) user interface object in response to detecting other deep press inputs. In some embodiments, the device enters the alternative mode in response to detecting a light press input (e.g., an input including an increase in intensity of a contact from an intensity below IT_(L) to an intensity above IT_(L)) during selection of a first user interface object and the device selects a second (or third, fourth, etc.) user interface object in response to detecting other light press inputs.

In response to detecting the second press input, the device selects (17528) the second user interface object and maintains selection of the first user interface object, as shown, for example, in FIGS. 8L-8O, where the device selects thumbnail 17402-2 in response to detecting an increase in intensity of contact 17410 from an intensity below IT_(L) to an intensity above IT_(L). In some embodiments, also shown in FIGS. 8L-8O, after selecting (17530) the first user interface object the device displays a first residual image (e.g., residual image 17416-1 in FIGS. 8J-8O) at the original location of the first user interface object, and after selecting the second user interface object the device displays a second residual image (e.g., residual image 17416-2 in FIG. 8O) at the original location of the second user interface object. In some embodiments, the residual images remain in place even while the focus selector (and, optionally, representations of the user interface objects) are moved on the display until the user interface objects are moved to a different location in the user interface (e.g., as shown in FIG. 8P).

In some embodiments, after (17532) displaying the first residual image and the second residual image the device detects (17534) an end of selection of the first user interface object and the second user interface object. For example, the device detects an invalid drop of the selected user interface objects such as liftoff (or deep press/double tap) of the contact while the focus selector is over a region of the display that the selected objects cannot be placed in. In response to detecting the end of selection of the first user interface object and the second user interface object, the device displays (17536) an animation of a representation of the first user interface object moving back to the first residual image and displaying an animation of a representation of the second user interface object moving back to the second residual image. For example, in FIG. 8O, when the device detects a valid drop operation, thumbnails 17402-1 and 17402-2 are dropped at a location proximate to cursor 17408, as shown in FIG. 8P. In contrast, in some embodiments, if the device detected an invalid drop operation in FIG. 8O, the device would display an animation of thumbnail 17402-1 and 17402-2 moving back to residual images 17416-1 and 17416-2, to return to the state of the user interface shown in FIG. 8F.

In some embodiments, the device detects (17538) a press input on a respective residual image (e.g., the device detects an increase in intensity of a contact corresponding to cursor 17408 above IT_(L) while the cursor is over the respective residual image). In response to detecting the press input on the respective residual image, the device deselects (17540) a user interface object corresponding to the respective residual image (e.g., deselect the first user interface object if the respective residual image is the first residual image and deselect the second user interface object if the respective residual image is the second residual image). In some embodiments, after the user interface object is deselected, the user interface object is displayed at its original location and the representation of the user interface object that was previously moving in accordance with movement of the focus selector and the respective residual image cease to be displayed.

In some embodiments, after selecting the first user interface object, the device displays (17542) a representation of the first user interface object proximate to the focus selector, and, after selecting the second user interface object, the device displays a representation of the second user interface object proximate to the focus selector (e.g., representations of a pile of photos follow cursor/contact around display). Examples of representations of user interface objects proximate to the focus selector include the “stack” or “pile” of user interface objects shown in, for example, FIG. 8O representing thumbnails 17402-1 and 17402-2.

In some embodiments, after selecting the first user interface object, the devices changes (17544) display of the first user interface object to provide a visual indication that the first user interface object has been selected (e.g., the border of thumbnail 17418-1 changes between FIG. 8Y and FIG. 8Z to show that thumbnail 17418-1 has been selected), and after selecting the second user interface object, the device changes display of the second user interface object to provide a visual indication that the second user interface object has been selected (e.g., the border of thumbnail 17418-7 changes between FIG. 8AA and FIG. 8BB to show that thumbnail 17418-7 has been selected). As one example, multiple thumbnails are simultaneously popped up off of the page (e.g., using a drop shadow or pseudo three dimensional effect) to provide a visual indication that user interface objects corresponding to the popped up images have been selected. As another example, residual images of thumbnails are displayed to provide a visual indication that user interface objects corresponding to the residual images have been selected.

In some embodiments, after (17546) selecting the first user interface object and the second user interface object, the device detects (17548) liftoff of the second contact. After detecting liftoff of the second contact, the device detects (17550) a third press input corresponding to a third contact. In response to detecting the third press input, the device deselects (17552) the first user interface object and the second user interface object (e.g., in FIG. 8DD, in response to detecting a contact 17416 that does not correspond to a selectable user interface object 17418, the device cancels the selection and exits the “select multiple objects” mode).

In some embodiments, the device detects (17554) a third press input that includes an increase in intensity of a contact above the alternative-mode intensity threshold (e.g., while the focus selector is at a location on the display that is outside of the plurality of user interface objects). In response to detecting the third press input, the device deselects (17556) the first user interface object and the second user interface object. In some embodiments, the first and second user interface objects are deselected if the increase in intensity is detected while the focus selector is over a portion of the user interface that does not include any selectable user interface objects, whereas if the increase in intensity is detected while the focus selector is over a third user interface object that is selectable, the third user interface object is selected in addition to the previously selected first and second user interface objects. For example, if the device were to detect an deep press input in FIG. 8DD while cursor 17411 is over thumbnail 17418-2 instead of over a portion of the user interface that does not include any of the thumbnails, then thumbnail 17418-2 would be selected in addition to thumbnails 17418-1 and 17418-7 instead of deselecting thumbnails 17418-1 and 17418-7, as shown in FIG. 8DD.

In some embodiments, the device detects (17558) liftoff of the continuously detected contact. In response to detecting liftoff of the continuously detected contact, the device deselects (17560) the first user interface object and the second user interface object (e.g., simultaneous selection of the multiple user interface object is maintained until the contact used to select the user interface objects is lifted off of the touch-sensitive surface), as shown in FIG. 8P, where the device deselects thumbnails 17402-1 and 17402-2 in response to detecting liftoff of contact 17410 from the touch-sensitive surface 451.

In some embodiments, the plurality of user interface objects includes (17562) a third user interface object that is representative of a collection of user interface objects (e.g., a folder icon that is representative of a directory of files, such as “docs” folder 17404 in FIG. 8A). After detecting selection of the first user interface object and the second user interface object (17564), the device detects (17566) a third press input that corresponds to an increase in intensity of a contact on the touch-sensitive surface while a focus selector is over the third user interface object. In some of these embodiments, in response (17568) to detecting the third press input, in accordance with a determination that the third press input includes an increase in intensity above the first intensity threshold (for example, contact 17410 has an intensity above IT_(D) as shown in 174U), the device displays (17570) a user interface with a region for adding the first user interface object and second user interface object to the collection of user interface objects represented by the third user interface object (e.g., opening the file in a file manager program, for example, as shown in FIGS. 8V-8X), and in accordance with a determination that the third press input includes an increase in intensity to a maximum intensity that is above the second intensity threshold (e.g., “IT_(L)”) and below the first intensity threshold (e.g., “IT_(D)”), the device selects (17572) the third user interface object in addition to the first user interface object and the second user interface object (e.g., in response to detecting the press input in FIG. 8S, the device picks up the folder icon, as shown in FIGS. 8S-8T). In some embodiments, if the increase in intensity of the contact is below the second intensity threshold (e.g., “IT_(L)”), the device forgoes performing an operation associated with the third user interface object.

It should be understood that the particular order in which the operations in FIGS. 9A-9E have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method 17500 described above with respect to FIGS. 9A-9E. For example, the contacts, press inputs, user interface objects, intensity thresholds, focus selectors described above with reference to method 17500 optionally have one or more of the characteristics of the contacts, press inputs, user interface objects, intensity thresholds, focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here.

In accordance with some embodiments, FIG. 10 shows a functional block diagram of an electronic device 17600 configured in accordance with the principles of the various described embodiments. The functional blocks of the device are, optionally, implemented by hardware, software, or a combination of hardware and software to carry out the principles of the various described embodiments. It is understood by persons of skill in the art that the functional blocks described in FIG. 10 are, optionally, combined or separated into sub-blocks to implement the principles of the various described embodiments. Therefore, the description herein optionally supports any possible combination or separation or further definition of the functional blocks described herein.

As shown in FIG. 10, an electronic device 17600 includes a display unit 17602 configured to display a graphic user interface, a touch-sensitive surface unit 17604 configured to receive contacts, one or more sensor units 17606 configured to detect intensity of contacts with the touch-sensitive surface unit 17604; and a processing unit 17608 coupled to the display unit 17602, the touch-sensitive surface unit 17604 and the one or more sensor units 17606. In some embodiments, the processing unit 17608 includes a detecting unit 17610, a display enabling unit 17612, and a selecting unit 17614.

Display unit 17602 is configured to display a plurality of user interface objects, including a first user interface object and a second user interface object. Processing unit 17608 is configured to detect a first press input (e.g., with the detecting unit 17610) that corresponds to an increase in intensity of a contact above a first intensity threshold on the touch-sensitive surface unit 17604 while a focus selector is over the first user interface object. In response to detection of the first press input, processing unit 17608 is configured to select the first user interface object (e.g., with the selecting unit 17614), and after selecting the first user interface object, detect a second press input (e.g., with the detecting unit 17610) that corresponds to an increase in intensity of a contact above a second intensity threshold on the touch-sensitive surface unit 17604 while the focus selector is over the second user interface object. In response to detection of the second press input, processing unit 17608 is configured to select the second user interface object (e.g., with the selecting unit 17614) and maintaining selection of the first user interface object.

In some embodiments, the first press input corresponds to a first contact on the touch-sensitive surface unit, and the second press input corresponds to a second contact on the touch-sensitive surface unit different from the first contact.

In some embodiments, the processing unit 17608 is further configured to, after selecting the first user interface object and the second user interface object, detect liftoff of the second contact. After detecting liftoff of the second contact, processing unit 17608 is further configured to detect a third press input (e.g., with the detecting unit 17610) corresponding to a third contact; and, in response to detecting the third press input, deselect the first user interface object and the second user interface object (e.g., with the selecting unit 17614).

In some embodiments, the first press input and the second press input are portions of a single gesture that includes a continuously detected contact on the touch-sensitive surface unit 17604.

In some embodiments, the processing unit 17608 is further configured to, after selecting the first user interface object and the second user interface object, detect liftoff (e.g., with the detecting unit 17610) of the continuously detected contact; and in response to detecting liftoff of the continuously detected contact, deselect the first user interface object and the second user interface object (e.g., with the selecting unit 17614).

In some embodiments, the first press input and the second press input are portions of a single gesture that includes a continuously detected contact on the touch-sensitive surface unit; and the gesture includes an intermediate portion between the first press input and the second press input that includes movement of the continuously detected contact corresponding to movement of the focus selector from the first user interface object to the second user interface object.

In some embodiments, the processing unit 17608 is configured to detect a range of contact intensity values and compare the detected intensity values against a plurality of different intensity thresholds. The plurality of different intensity thresholds include an alternative-mode intensity threshold that is used by the processing unit 17608 to transition from a first selection mode to a second selection mode; and a selection intensity threshold that is used by the processing unit 17608 to differentiate between inputs that correspond to movement of the focus selector on the display unit 17602 (and inputs that correspond to selection of a user interface object at a location on the display unit 17602 at or near a location of the focus selector, where the selection intensity threshold is different from the alternative-mode intensity threshold.

In some embodiments, processing unit 17608 is further configured to, after selecting the first user interface object and the second user interface object, detect a third press input (e.g., with the detecting unit 17610) that includes an increase in intensity of a contact above the alternative-mode intensity threshold; and in response to detecting the third press input, deselect the first user interface object and the second user interface object (e.g., with the selecting unit 17614).

In some embodiments, the first intensity threshold is the alternative-mode intensity threshold, and the second intensity threshold is the alternative-mode intensity threshold.

In some embodiments, the first intensity threshold is the alternative-mode intensity threshold, and the second intensity threshold is the selection intensity threshold.

In some embodiments, the plurality of user interface objects includes a third user interface object that is representative of a collection of user interface objects, and the processing unit 17608 is further configured to, after selecting the second user interface object, detect (e.g., with the detecting unit 17610) a third press input that corresponds to an increase in intensity of a contact on the touch-sensitive surface unit 17604 while a focus selector is over the third user interface object. The processing unit 17608 is further configured to, in response to detecting the third press input, in accordance with a determination that the third press input includes an increase in intensity above the first intensity threshold, display a user interface (e.g., with the display enabling unit 17612) with a region for adding the first user interface object and second user interface object to the collection of user interface objects represented by the third user interface object and, in accordance with a determination that the third press input includes an increase in intensity to a maximum intensity that is above the second intensity threshold and below the first intensity threshold, select the third user interface object (e.g., with the selecting unit 17614) in addition to the first user interface object and the second user interface object.

In some embodiments, the processing unit 17608 is further configured to, after selecting the first user interface object, display a first residual image (e.g., with the display enabling unit 17612) at the original location of the first user interface object; and after selecting the second user interface object, display a second residual image (e.g., with the display enabling unit 17612) at the original location of the second user interface object.

In some embodiments, the processing unit 17608 is further configured to, after displaying the first residual image and the second residual image, detect (e.g., with the detecting unit 17610) an end of selection of the first user interface object and the second user interface object and in response to detecting the end of selection of the first user interface object and the second user interface object, display an animation (e.g., with the display enabling unit 17612) of a representation of the first user interface object moving back to the first residual image and display an animation (e.g., with the display enabling unit 17612) of a representation of the second user interface object moving back to the second residual image.

In some embodiments, the processing unit 17608 is further configured to, after displaying the first residual image and the second residual image, detect a press input (e.g., with the detecting unit 17610) on a respective residual image, and, in response to detecting the press input on the respective residual image, deselect a user interface object (e.g., with the selecting unit 17614) corresponding to the respective residual image.

In some embodiments, the processing unit 17608 is further configured to, after selecting the first user interface object, display a representation of the first user interface object (e.g., with the display enabling unit 17612) proximate to the focus selector; and, after selecting the second user interface object, display a representation of the second user interface object (e.g., with the display enabling unit 17612) proximate to the focus selector.

In some embodiments, processing unit 17608 is further configured to, after selecting the first user interface object, change display of the first user interface object (e.g., with the display enabling unit 17612) to provide a visual indication that the first user interface object has been selected; and, after selecting the second user interface object, change display of the second user interface object (e.g., with the display enabling unit 17612) to provide a visual indication that the second user interface object has been selected.

The operations in the information processing methods described above are, optionally implemented by running one or more functional modules in information processing apparatus such as general purpose processors (e.g., as described above with respect to FIGS. 1A and 3) or application specific chips.

The operations described above with reference to FIGS. 9A-9E are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 10. For example, detection operations 17510 and 17512, and selection operations 17512 and 17528, and deselecting operation 17540 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

Typing Characters on a Virtual Keyboard

Many electronic devices with touch-sensitive surfaces, such as portable multifunction devices with touch screen displays, have graphical user interfaces with displayed virtual keyboards for typing characters for output in, for example, e-mail messages, notepad applications, and search fields. Some methods for entering a character or a sequence of characters (e.g., entering an input into the device that corresponds to a request to output a character or multiple characters) require separate contacts on a touch-sensitive surface for each character entered. However, entering characters with a separate contact for each character entered can be inefficient and time consuming for a user.

In the embodiments described below, a faster and more efficient method for accurately typing characters on a virtual keyboard is provided where a sequence of characters can be selected with a continuous contact in response to detecting an increase in intensity of the contact while the contact is over keys corresponding to the characters. In some embodiments, detecting a press input that includes a contact with a respective intensity above a respective threshold (e.g., on a device with a touch-sensitive surface configured to detect intensity of contacts) while a contact is over a respective character causes the device to output the respective character. In contrast, detecting a press input with a maximum intensity below the respective threshold causes the device to forgo outputting the respective character. This method streamlines the character typing process by allowing a user to type characters quickly and accurately using a single continuous movement of a contact.

FIGS. 11A-11T illustrate exemplary user interfaces for typing characters on a virtual keyboard in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes described below, including the processes in FIGS. 12A-12D. FIGS. 11B-11T include intensity diagrams that show the current intensity of the contact on the touch-sensitive surface relative to a plurality of intensity thresholds including a first intensity threshold (e.g., “IT_(L)”), a deep press intensity threshold (e.g., “IT_(D)”) and a character output intensity threshold (e.g., “IT_(C)”).

FIG. 11A illustrates an exemplary user interface displayed on device 300 with touch screen 112 for typing characters on a virtual keyboard 17704 in accordance with some embodiments. As an example, the device displays a notepad application (app) 17702. Letters and/or other characters produced using inputs (gestures, contacts, etc.) are outputted (e.g., displayed) in the notepad within notepad app 17702.

FIG. 11B illustrates detection of a contact 17706 on touch screen 112. Contact 17706 is detected by virtue of an intensity of contact above a minimum contact intensity threshold IT₀. However, in FIG. 11B, contact 17706 has an intensity below the light press intensity threshold IT_(L), and therefore no characters are outputted in notepad app 17702 (as described with reference to method 17800, FIGS. 12A-12D). FIG. 11B also illustrates movement of contact 17706 from the location shown in the figure to a location over the key corresponding to character “G.”

FIG. 11C illustrates an intensity of contact 17706 below IT_(L) while contact 17706 is over the key corresponding to character “G.” Optionally, the device displays a pop-up tab 17708 displaying a character that corresponds to the location of contact 17706. For example, because contact 17706 is currently over a hit-region that corresponds to the character “G”, the character “G” is displayed in the pop-up tab. The pop-up tab therefore allows a user to see a character to which a contact corresponds despite that character being covered by the user's finger. In this example, pop-up tab 17708 is displayed regardless of the intensity (e.g., without necessarily outputting the character “G,” as explained below).

FIG. 11D illustrates an intensity of contact 17706 above IT_(L) while contact 17706 is over the key corresponding to character “G” (e.g., a light press input is detected over the key corresponding to character “G”). Because character-output criteria are met, character “G” is outputted in notepad app 17702 (as described with reference to method 17800, FIGS. 12A-12D). In some embodiments, character “G” is outputted when an increase in intensity of contact 17706 is detected above IT_(L) (e.g., on the rising edge of intensity, or “down-stroke” of a contact, that subsequently has an intensity above IT_(L)). For example, in FIG. 11D, character “G” is output when an intensity of contact 17706 is above IT_(L) while contact 17706 is over the key corresponding to character “G” on the virtual keyboard.

In some embodiments, character “G” is outputted when a decrease in intensity of contact 17706 is detected from above IT_(L) to below IT_(L) (e.g., on the falling edge, or “up-stroke” of a contact that previously had an intensity above IT_(L)). In some embodiments, the character-output criteria include detection of both an intensity of contact 17706 above IT_(L), and a subsequent decrease in intensity from above to below a different character-output intensity threshold (e.g., IT_(C)), while contact 17706 is continuously detected over the key corresponding to character “G” on the virtual keyboard. In such embodiments, there are different thresholds to activate potential output of a character (e.g., IT_(L)) and to actually trigger output of the character (e.g., IT_(C)), thereby providing hysteresis and prevented repeated, accidental outputs of the same character. Alternatively, in some embodiments, IT_(L) and IT_(C) are equal. For ease of explanation, output of a respective character is shown contemporaneously with a corresponding input above IT_(L), unless otherwise noted (e.g., output is triggered on the down-stroke).

In some embodiments, after output of a capitalized character (e.g., character “G”) virtual keyboard 17704 automatically transitions to displaying lower-case characters. In some embodiments, subsequent fulfillment of character-output criteria while a contact is over a lower-case character (e.g., “g”) results in output of the lower-case character. For convenience of explanation, embodiments are described with reference to capitalized (i.e., upper-case) characters.

FIG. 11D also illustrates subsequent movement of contact 17706 to a location over the key corresponding to character “F.”

FIG. 11E illustrates a maximum intensity of contact 17706 below IT_(L) while contact 17706 is over the key corresponding to character “F.” In this example, intensity of contact 17706 remains below IT_(L) during the period of time in which contact 17706 is over the key corresponding to character “F.” As a result, the device forgoes outputting character “F” in notepad app 17702 (as described with reference to method 17800, FIGS. 12A-12D). FIG. 11E also illustrates subsequent movement of contact 17706 to a location over the key corresponding to character “E.”

FIG. 11F illustrate an intensity of contact 17706 below IT_(L) while contact 17706 is over the key corresponding to character “E.”

FIG. 11G illustrates an increase in intensity of contact 17706 from below IT_(L) to above IT_(L) and the resulting output of a character “E.”

FIG. 11H illustrates subsequent movement of contact 17706 to a location over the key corresponding to character “R.” The device forgoes output of the character “R”, as shown in FIG. 11I, because the intensity of contact 17706 remains below IT_(L) while contact 17706 is over the key corresponding to character “R.”

FIGS. 11J-11M illustrate exemplary user interfaces for sequentially outputting more than one instance of the same character. FIG. 11J illustrates contact 17706 at a location over the key corresponding to character “T.” FIG. 11K illustrates the intensity of contact 17706 above IT_(L) and the resulting output of the character “T” as described above. FIG. 11L shows a decrease in intensity below IT_(C). FIG. 11M illustrates a subsequent intensity of contact 17706 above IT_(L) (e.g., contact 17706 has an intensity above IT_(L) for a second time with an intermediate detection of contact 17706 with an intensity below IT_(C)). As a result, a second instance of the character “T” is outputted in notepad app 17702.

FIG. 11M also illustrates display of an autocorrect and/or auto-complete interface displaying a suggested correction and/or completion to a user outputted string of characters (e.g., “GETT” in the instant example). In this example, the device suggests the correction and completion “JETTY” to replace the outputted “GETT.” FIG. 11M also illustrates subsequent movement of contact 17706 to a location over a space-bar (it is not necessarily required that the intensity of contact 17706 is above any particular threshold during movement of contact 17706). In this example, the space-bar is a predefined affordance for accepting or declining the autocorrect/auto-complete suggestion. In some embodiments, detection of a light press input (e.g., an increase in intensity of contact 17706 from an intensity below IT_(L) to an intensity above IT_(L), optionally followed by a decrease in intensity of contact 17706 below IT_(L)) while contact 17706 is over the predefined affordance (e.g., the space-bar) results in acceptance (and output) of the suggestion (shown in FIGS. 11O-11P). In some embodiments, detection of a deep press input (e.g., an increase in intensity of contact 17706 from an intensity below IT_(D) to an intensity above IT_(D), optionally followed by a decrease in intensity of contact 17706 below IT_(D)) while contact 17706 is over the predefined affordance preempts (declines) the suggestion and results in continued display of the user outputted string of characters (shown in FIGS. 11Q-11R). Alternatively, in some embodiments, a deep press results in acceptance of the suggestion and a light press results in preemption (e.g., rejection) of the suggestion (e.g., the functionality is reversed compared with the embodiments described with reference to FIGS. 11M-11S).

FIG. 11T illustrates an intensity of a contact 17710 above the deep press intensity threshold IT_(D). In some embodiments, detection of an intensity of contact 17710 above IT_(D) results in display of a special character interface displaying special characters (e.g., an “e” character with: grave accent, acute accent, dot above, ogonek, and diaeresis). In some embodiments, selection of a particular displayed special character results in the output of the particular displayed special character in notepad 17702 (e.g., in lieu of outputting the character “E”).

FIGS. 12A-12D are flow diagrams illustrating a method 17800 of typing characters on a virtual keyboard in accordance with some embodiments. The method 17800 is performed at an electronic device (e.g., device 300, FIG. 3, or portable multifunction device 100, FIG. 1A) with a display and a touch-sensitive surface. In some embodiments, the display is a touch screen display and the touch-sensitive surface is on the display. In some embodiments, the display is separate from the touch-sensitive surface. Some operations in method 17800 are, optionally, combined and/or the order of some operations is, optionally, changed.

As described below, the method 17800 provides an intuitive way to typing characters on a virtual keyboard. The method reduces the cognitive burden on a user when typing characters on a virtual keyboard, thereby creating a more efficient human-machine interface. For battery-operated electronic devices, enabling a user to type characters on a virtual keyboard faster and more efficiently conserves power and increases the time between battery charges.

The device displays (17802) a virtual keyboard on the display (e.g., an alphanumeric keyboard for entering text on the device shown in FIG. 11A). The device detects (17804) a contact on the touch-sensitive surface (e.g., contact 17706, FIG. 11B). While continuously detecting (17806) the contact on the touch-sensitive surface, the device detects (17808) one or more movements of the contact on the touch-sensitive surface that correspond to movement of a focus selector over the virtual keyboard (e.g., a single continuous movement over multiple keys of the virtual keyboard such as contact 17706 in FIG. 11B, and/or a plurality of discrete movements from one key to another such as contact 17706 in FIG. 11E). For each respective key of a plurality of keys of the virtual keyboard, while detecting the focus selector over a respective key of the plurality of keys, in accordance with a determination that character-output criteria for outputting a character that corresponds to the respective key have been met, where the character-output criteria include that a respective intensity of the contact is above a first intensity threshold, while detecting the focus selector over the respective key, the device outputs (17810) the character, and in accordance with a determination that the character-output criteria have not been met, the device forgoes outputting the character that corresponds to the respective key. In some embodiments, the first intensity threshold is an intensity threshold that is higher than an input-detection intensity threshold at which the contact is initially detected. In some embodiments, the character is output in response to detecting an increase in intensity of the contact from an intensity below the first intensity threshold to an intensity above the first intensity threshold.

In some embodiments, the character-output criteria for outputting the character that corresponds to the respective key include (17811) that, while the focus selector is over the respective key, the contact corresponding to the focus selector increases from an intensity below the first intensity threshold (e.g., the character is output in response to detecting an increase in intensity of the contact from an intensity below the first intensity threshold to an intensity above the first intensity threshold).

In some embodiments, the character-output criteria for outputting the character that corresponds to the respective key include (17812) that, while the focus selector is over the respective key, the contact corresponding to the focus selector decreases from an intensity above the first intensity threshold to an intensity below a character-output intensity threshold. In some embodiments, the character-output intensity threshold is the same as the first intensity threshold. In some embodiments, the character-output intensity threshold is below the first intensity threshold.

In some embodiments, the character-output criteria for outputting the character that corresponds to the respective key include (17813) that, while the focus selector is continuously detected over the respective key, the contact corresponding to the focus selector increases from an intensity below the first intensity and subsequently decreases from an intensity above the first intensity threshold to an intensity below a character-output intensity threshold (e.g., the character-output criteria include detection of a down-stroke and an up-stroke while the contact is continuously over a respective key).

In some embodiments, while continuously detecting the contact on the touch-sensitive surface, the device detects (17814) a first press input that includes detecting an increase in intensity of the contact above the first intensity threshold while the focus selector is over a first key. In response to detecting the first press input, the device outputs (17815) a character that corresponds to the first key. In some embodiments, the device outputs the character in response to detecting the increase in intensity of the contact above the first intensity threshold (e.g., the “down-stroke” of the press input). In some embodiments, the device outputs the character in response to detecting the decrease in intensity of the contact below the character-output intensity threshold (e.g., the “up-stroke” of the press input).

In some embodiments, while continuously detecting the contact on the touch-sensitive surface, the device detects a decrease in intensity of the contact below the first intensity threshold. After detecting the decrease in intensity of the contact below the first intensity threshold, the device detects (17816) a decrease in intensity of the contact below the first intensity threshold (or, optionally, the character-output intensity threshold). After detecting the decrease in intensity of the contact below the first intensity threshold, the device detects (17818) a second press input (or, in some circumstances a third, fourth, etc.) that includes detecting an increase in intensity of the contact above the first intensity threshold while the focus selector is over the first key. In response to detecting the second press input, the device outputs (17820) a character that corresponds to the first key again as an additional output (e.g., output of a second character “T,” FIGS. 11J-11M). Thus, in some embodiments, the first key can be selected twice as an output for the keyboard without detecting liftoff of the contact. For example, a user can keep a contact over the “A” key and perform an increase pressure, decrease pressure, increase pressure sequence to select the key twice (e.g., to type “AA”). Similarly, the user can use a single continuous contact with multiple increase pressure, decrease pressure cycles while the focus selector is over multiple keys (e.g., the “A” key and the “B” key) to type sequences of characters (e.g., “ABAB”). In some embodiments, the device outputs the character in response to detecting the increase in intensity of the contact above the first intensity threshold (e.g., the “down-stroke” of the press input). In some embodiments, the device outputs the character in response to detecting the decrease in intensity of the contact below the character-output intensity threshold (e.g., the “up-stroke” of the press input).

In some embodiments, while continuously detecting the contact on the touch-sensitive surface, the device detects (17822) a second press input that includes detecting an increase in intensity of the contact above the first intensity threshold while the focus selector is over a second key. In response to detecting the second press input (17824) a character that corresponds to the second key (e.g., as the user moves the focus selector around the keyboard, multiple different keys can be selected by increasing the intensity of the contact while the focus selector is over different keys in the keyboard). In some embodiments, the device outputs the character in response to detecting the increase in intensity of the contact above the first intensity threshold (e.g., the “down-stroke” of the press input). In some embodiments, the device outputs the character in response to detecting the decrease in intensity of the contact below the character-output intensity threshold (e.g., the “up-stroke” of the press input).

In some embodiments, while continuously detecting the contact on the touch-sensitive surface, the device detects (17826) movement of the contact that corresponds to movement of the focus selector over a second key, and a maximum intensity of the contact is below the first intensity threshold while the focus selector is over the second key. In response to detecting movement of the contact that corresponds to movement of the focus selector over the second key, wherein the maximum intensity of the contact is below the first intensity threshold while the focus selector is over the second key, the device forgoes (17828) outputting a character that corresponds to the second key.

In some embodiments, while continuously detecting the contact on the touch-sensitive surface, the device detects (17830) a plurality of inputs that correspond to entering a sequence of characters (e.g., sequence of characters “GETT,” FIG. 11M). In response to detecting the plurality of inputs, the device displays (17832) an autocorrect user interface for changing the sequence of characters to a modified sequence of characters (e.g., display an autocorrected sequence of characters such as autocorrected sequence “JETTY,” FIG. 11M, with a cancellation affordance or display one or more autocorrect options for replacing the sequence of characters). While displaying the autocorrect user interface, the device detects (17834) an autocorrect input that includes an increase in intensity of the contact above the first intensity threshold while the focus selector is over a respective affordance (e.g., a space bar or a delete key) in the user interface. In response to detecting the autocorrect input, in accordance with a determination that the contact included in the autocorrect input has an intensity above a second intensity threshold that is higher than the first intensity threshold, the device performs (17836) a first operation associated with the sequence of characters.

In some embodiments, in response to detecting the autocorrect input, in accordance with a determination that the contact included in the autocorrect input has an intensity between the first intensity threshold and the second intensity threshold, the device performs (17838) a second operation associated with the sequence of characters, the second operation being different from the first operation.

In some embodiments, the first operation includes (17840) rejecting the modified sequence of characters (e.g., rejecting the suggested auto-correction, FIGS. 11Q-11S), and the second operation includes replacing the sequence of characters with the modified sequence of characters (e.g., accepting the suggested auto-correction, FIGS. 11O-11P).

Alternatively, in some embodiments, the first operation includes (17842) replacing the sequences of characters with the modified sequence of characters, and the second operation includes rejecting the modified sequence of characters.

It should be understood that the particular order in which the operations in FIGS. 12A-12D have been described is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that details of other processes described herein with respect to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) are also applicable in an analogous manner to method 17800 described above with respect to FIGS. 12A-12D. For example, the contacts, gestures, characters, intensity thresholds, and focus selectors described above with reference to method 17800 optionally have one or more of the characteristics of the contacts, gestures, characters, intensity thresholds, and focus selectors described herein with reference to other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments). For brevity, these details are not repeated here.

The operations described above with reference to FIGS. 12A-12D are, optionally, implemented by components depicted in FIGS. 1A-1B or FIG. 13. For example, detection operation 17804, output operation 17810, and autocorrect operation 17836 are, optionally, implemented by event sorter 170, event recognizer 180, and event handler 190. Event monitor 171 in event sorter 170 detects a contact on touch-sensitive display 112, and event dispatcher module 174 delivers the event information to application 136-1. A respective event recognizer 180 of application 136-1 compares the event information to respective event definitions 186, and determines whether a first contact at a first location on the touch-sensitive surface corresponds to a predefined event or sub-event, such as selection of an object on a user interface. When a respective predefined event or sub-event is detected, event recognizer 180 activates an event handler 190 associated with the detection of the event or sub-event. Event handler 190 optionally utilizes or calls data updater 176 or object updater 177 to update the application internal state 192. In some embodiments, event handler 190 accesses a respective GUI updater 178 to update what is displayed by the application. Similarly, it would be clear to a person having ordinary skill in the art how other processes can be implemented based on the components depicted in FIGS. 1A-1B.

It should be understood that the particular order in which the operations have been described above is merely exemplary and is not intended to indicate that the described order is the only order in which the operations could be performed. One of ordinary skill in the art would recognize various ways to reorder the operations described herein. Additionally, it should be noted that the various processes separately described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) can be combined with each other in different arrangements. For example, the contacts, user interface objects, tactile sensations, intensity thresholds, and/or focus selectors described above with reference to any one of the various processes separately described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments) optionally have one or more of the characteristics of the contacts, gestures, user interface objects, tactile sensations, intensity thresholds, and focus selectors described herein with reference to one or more of the other methods described herein (e.g., those listed in the fifth paragraph of the Description of Embodiments).
